If you meet in technical devices Designation: USB TYPE-A, USB Type-B Or USB Type-C, this means that such types of sections are used in the USB device.
This is not a designation of the USB standard, this is the designation of the type of type.

The standards of the USB or their versions are indicated as follows: USB 1.0, USB 1.1, USB 2.0, USB 3.0 and USB 3.1.
Moreover, USB 3.1 has two versions: USB 3.1 Gen 1 and USB 3.1 Gen 2.

The most famous type of USB sections is USB Type-A, it is located on flash drives, USB modems, on the ends of the wires of mice and keyboards.

It is used for USB 1.0 standards, USB 1.1, USB 2.0 and USB 3.0.
For USB 1.0, USB 1.1, USB 2.0 Speake has a black color, and for USB 3.0 - blue.
Thanks to the time USB Type-A devices With standards to USB 3.0 are compatible.

Severe USB Type-C differs from previous ones and are not compatible with them.

If there is a need to combine, then you need to use the appropriate adapters.

An important advantage of the USB Type-C mode is that it is symmetrical.
Now no longer have to worry about which side to insert the cable into the device, i.e. A plug type C can be inserted with any side into the socket.

Now we'll figure it out in the difference of USB standards.
Theoretical data transfer rate:

USB 1.0 to 1.5 Mbps
- USB 1.1 to 12 Mbps
- USB 2.0 to 480 Mbps
- USB 3.0 and USB 3.1 Gen 1 to 5 Gb / s
- USB 3.1 Gen 2 to 10 Gb / s

The supply voltage, maximum current and power consumed by the peripheral device:

USB 1.0, USB 1.1 - up to 150 mA 5 V (0.75 W)
USB 2.0 - 5V to 500 mA (2.5 W)
USB 3.0 - 5V to 900 mA (4.5 W)
USB 3.1 Current @ 1.5 A - 5V to 1.5 A (7.5 W)
USB 3.1 CURRENT @ 3 A - 5V to 3A (15 W)
USB 3.1 (with Power Delivery 2.0 support) and depending on Profile:
PROFILE1 - 5V 2A (10 W)
PROFILE2 - 5V 2A, 12V 1,5A (18 W)
PROFILE3 - 5V 2A, 12V 3A (36 W)
PROFILE4 - 5V 2A, 12V, 20V 3A (60 W)
PROFILE5 - 5V 2A, 12V, 20V 5A (100 W)

The power profile system is introduced for more advanced cases, Profile1 is used for the standard devices.
For example, an advanced case can be considered an active USB cable 100 meters having a USB interface signal converter to optical and vice versa (maximum length standard USB The cable cannot exceed 5 meters).
Such a cable transmits only data, and the power is necessary for converters.

Therefore, it is necessary to know the power profiles as connected peripheral devicesand the main device to which the connection is performed.
The port on the device corresponding to the higher level profile supports all the states of the previous ones.

For example, a device with any profile can be connected to the device with PROFILE5.
We draw your attention to the fact that the USB cable must also correspond to the power profile if you connect the peripheral device of high power.

And last remark.
The presence on the USB Type-C mode device does not mean that this port in the device works according to USB 3.1.

The new USB Type-C standard is still not widely developed in the market, but manufacturers gradually accept fresh technology. In the USB-C smartphone, you can already be called a new trend, because it is not only an improved charging connector, but also a means for refusing a traditional 3.5-millimeter headphone port. Today we will talk in more detail about USB Type-C, and this article will tell you what it is.

Today, almost all electronic devices are equipped with a USB connector. From desktops to smartphones and a variety of drives with laptops. USB is an ubiquitous standard when it comes to connecting the periphery or data transmission between devices. The last major update of the USB was published in 2013 with the output of USB 3.1, accompanied by the release of the new Type-C connector. As you can see, since then almost 4 years has passed, and Type-C never passed.

Currently, in the market, you can recalculate devices using USB Type-C technology on the market. Among the computers is the latest Apple laptops, from Google, Samsung ruler and a few more hybrid devices. Among smartphones - mostly flagships of the outgoing year:, and.

So why usb. Type-C is betterWhat predecessors? Let's find out.

What is USB Type-C

USB Type-C is a new and currently actively developing sectoral data standard for computers and mobile devices. The main and most significant innovation of Type-C is a modified connector - a universal, symmetrical, capable of working by any side. The USB-C connector was invented by USB IMPLEMENTERS FORUM - a group of companies that developed and certified the new USB standard. It also includes the largest technological companies, namely, Apple, Samsung, Dell, HP, Intel and Microsoft. By the way, it is important to know, because therefore USB Type-C was easily accepted by most PC manufacturers.

USB-C is a new standard

First of all, you need to know that USB Type-C is a new standard for the industry. In the same way as they were usb 1.1, USB 2.0, USB 3.0 or the latest USB 3.1. Only previous generations of USB were more focused on increasing the rate of data transfer and various other improvements, while Type-C from a physical point of view changes the design of the connector similarly to the modifications of the technology - MicroUSB and MINIUSB. However, the decisive difference in this case is that, unlike microusb and miniusb, Type-C is aimed at replacing absolutely all standards, and from both sides (an example of USB-microusb).

Main characteristics:

• 24 signal output
• USB support 3.1.
• Alternative mode to implement third-party interfaces
• Speed \u200b\u200bup to 10 Gbps
• Energy transmission up to 100 W
• Dimensions: 8,34х2,56 mm

USB Type-C and USB 3.1

One of the possible questions of those who do not know about USB Type-C may be something similar: what does USB 3.1 ratio have to USB Type-C? The fact is that USB 3.1 is the main data transfer protocol for Type-C. The speed of version 3.1 is 10 Gbps per second - in theory it is 2 times faster than USB 3.0. More USB 3.1 can be presented in the original connector format - this port is called USB 3.1 Type-a. But today it is much easier to meet USB 3.1 with a new Type-C universal connector.

USB version

To better understand why Type-C becomes replacing the traditional version of USB, first of all it is necessary to understand the difference between them. There are various USB versions, as well as even different connectors - for example, Type-a and Type-b.

USB versions belong to the overall standard, but their difference is maximum speed Data transfer and capacity. Of course, there are many other factors.

USB 1.1.
Although USB 1.0 is technically the first version of the USB, it could not fully enter the market. Instead, a new version of USB 1.1 was released - just she became the first standard to which we were all accustomed. USB 1.1 may transmit data at a speed of 12 Mbps per second and consumes 100 mA currents.

USB 2.0
The second USB version was presented in April 2000. It provided a standard for significant increase in the maximum data transfer rate - up to 480 Mbps per second. Also, USB 2.0 has become more powerful by consuming 1,870 by 2.5V.

USB 3.0.
USB 3.0 yield brought with you not only the expected improvements in data transmission and power, but also new types of connectors. Moreover, USB 3.0 even got its color - new version The standards were designated blue to distinguish it from old USB generations. USB 3.0 can operate at a speed of up to 5 Gbps per second, taking 5V for its operation to 1,8a. By the way, this version was presented in November 2008.

USB 3.1.
Newest and Samem best version USB was released in July 2013, although it is still not used everywhere. USB 3.1 can provide users throughput up to 10 Gbps per second with maximum energy consumption in 5V / 1A, or optionally 5A / 12V (60 W) or 20V (100 W).

Type-A.
Type-A is a classic USB interface. The short and rectangular plug became an original design for USB and to this day remains a standard connector for use at the end of the USB cable host. There are also some variations of Type-A - Mini Type-a and Micro Type-A, but they have never been widely accepted by the public due to the complex socket. Currently, both of these variations of Type-A are recognized as outdated.

Type-B.
If Type-A has become one side of the usb cable familiar to us, then Type-B is another. The original TYPE-B is a high connector with beveled upper corners. Usually occurs on printers, although by itself is an extension of the USB 3.0 standard for introducing new connection capabilities. The classic miniusb and microUSB also exists in the Type-B version, along with absolutely clumsy microUSB 3.0, in which additional plugs are used.

Type-C.
Thus, after Type-a and Type-b, we approached, obviously, to the newest Type-c. Type-a and Type-B versions were to work together with each other by backward compatibility, but the arrival of Type-C completely destroyed these plans, since USB-C implies a complete replacement of outdated USB connection technologies. Also, Type-C was designed in a special way that additional options for MINI or Micro do not need to be released at all. This, again, is associated with the intentions to replace all the current connectors on USB Type-C.

The main feature of the Type-C standard is the versatility or symmetry of the connector. USB-C can be used by both parties like Apple Lightning technology - more than any special sides for the connection, which is also difficult to find in the dark. Also, the type-c version is based on USB 3.1, which means support for all benefits. latest version, including the highest speed.

USB-C is still inversely compatible with existing USB variants, but for such a use scenario, of course, adapters will need.

USB Type-C Disadvantages

The problems of the new USB Type-C standard are naturally also available. One of the main and most serious concerns of the latest version of the technology is called the physical design of the connector - it is very fragile due to symmetric design. Apple, despite the same versatility of its Lightning, uses a durable metal plug, which is much more resistant to external influences.

Even more relevant and considerable concern uSB problem Type-C is the unregulated connection of the connector, which led to a number of dangerous accessories in the sale. Some of these accessories through the use of unsupported voltage levels are able to "fry" the connected device. For example, it was so with magnificent at the start of the flagship, which later began to ignite first, and then explode in the hands, trousers, cars and apartments of their owners.

This problem led to an obvious and only solution - a massive ban on the production and sale of non-original accessories with support for USB Type-C. So, if the accessory does not meet the standard USB IMPLEMENTERS FORUM INC. INC., then the product will not be allowed to sell. Also, to test the working condition and authenticity of various third-party accessories, USB-IF introduced a 128-bit software encryption, which will allow devices with this connector to carry out automatic check Connected device or accessory with USB-C.

Minuses:

• Design.The design of USB Type-C is good, but the design suffered - it is rather fragile. Apple In its Lightning uses a all-metal plug when the oval form is used in Type-C with the placement of signal outputs in the central part.
• Connector operation.If you allow USB Type-C to work with unsupported voltage levels, then most likely the cable and / or the device will be ignited.
• Compatibility.USB Type-C is innovation in the USB world, but the newest generation Leaves old devices in the past, because it does not support work with them.
• Adapters.For full-fledged work with USB Type-C on old devices, adapters will have to arrive. This is an extra cost of money.

Advantages of USB Type-C

Despite all the above, USB Type-C can be confidently called a step forward for the industry. Installing this Connector will allow manufacturers to make thinner computers and mobile devices with fewer ports, the highest data transfer rate and headphones. In the future, if USB Type-C is mounted in the mass, the connector will be able to replace not only the port 3.5 mm for headphones, but also the HDMI - the interface used to transmit video. So USB Type-C will replace familiar connectors today and will become a universal standard in any situation.

Pros:

• Symmetry. USB Type-C allows you to forget about situations when you have to remember which side to insert the cable into the connector. From now on, you can not be afraid not to find the desired USB side in the dark.
• Compactness. The dimensions of USB Type-C are 8.4x2.6 mm - it allows manufacturers to make computers and mobile devices significantly thinner.
• Universality. Thanks to the integration of the single connector, it will be possible charging with one cable as a laptop and a tablet or a smartphone.

Two ten years ago, the USB nest was in the wonder even for desktop personal computer. But over time, the usual standard connector has become mini, and later micro appeared. To date, without an interface of this type, no mobile device is required. It is for this reason that it will not be at all unnecessary to find out how they are as arranged and for which the USB ports and micro-USB are served.

USB interface specification

With the development of computational equipment, the problem of the operational transmission of information between devices has become more relevant. Existing standards of serial and parallel ports could no longer satisfy the increasing needs and were extremely uncomfortable in use. In front of the designers the task of creating universal and, most importantly, easy to use the port With high transmission rate. They became a well-known USB interface - universal serial bus (Universal Serial Bus).

The first version of the port - USB 1.0 - did not differ in high data transfer rate (1.5 MB / s), but possessed the properties of versatility and ease of use. The interface is excellent to work with the most different periphery And, which is especially important, supported the "hot" connection and "Enable and Work" mode. True, the version turned out to be "raw" and worked unstable, so in 2 years the next specification was published - USB 1.1. It has been corrected USB version 1.0 errors.

USB 2.0 protocol saved all the advantages of the previous version and transmitted data at speeds up to 48 MB / s. This version of the specification was already much more useful than its senior fellow. She could support enough speed \u200b\u200bexternal drives And ensured the transfer of large amounts of information for a reasonable time. This version is considered to be the main one until today - it is with the USB 2.0 interface that the overwhelming majority of periphery and mobile devices are produced.

The USB 3.0 protocol version, which appeared 10 years ago, has even greater (up to 600 MB / s) bandwidth and is able to serve truly high-speed devices. Like predecessors, port is convenient to use and has the same architectural structure.So, allows you to connect external devices "on the fly" (hot connection) and independently recognizes them. The current USB 3.2 protocol is currently being developed, which will allow devices to exchange information at speeds to 2.5 GB / s.

USB connectors

Simultaneously with the development of the specification, new types of USB connectors were developed. This is due to the fact that a similar interface began to supply not only PCs and peripherals to them, but also a variety of gadgets, including miniature. The standard YUSB connector developed initially simply did not fit in compact mobile devices. To date, there are 3 main types of ports:

1. mini usb;
2. micro USB.

It is under them "sharpened" most of the peripheral devices and gadgets.

Three main types of USB connectors today

Normal USB socket

It is installed in PCs, laptops and periphery to them - printers, external drives, routers, etc. The same sockets have universal network adapters.

Standard USB Nests in PC and Network Charger

The fork to such a type of nests is equipped with peripheral devices - mice, keyboards, external drives, radio modulus, etc. The same forks can be seen in adapter cables from one type of connector to another:

USB Cable - Micro USB

USB MINI interface

This type of interface was designed for miniature devices requiring information transfer - the usual nest in them simply does not fit. Especially this standard did not arrive because sufficiently bulky outlet designBut today there are a lot of gadgets using such a type of connectors. For pairing with other types, as mentioned above, adapter cables are produced.

Player with mini yusb and transition cord for him

Micro USB connector

To date, this type of connectors is standard for small-sized devices - almost all gadgets are equipped with phones and tablets to players, navigators and cameras. Despite their own compactness and seeming harnessThe design with the appropriate handling is quite durable, reliable and durable. Following this standard, even devices are equipped with such nests, which are absolutely not needing information transmission - lanterns, radio receivers, wireless headphones And so on. For what is the same flashlight data interface? True, nothing. And the socket in such devices is used to supply external power supply and charging the built-in batteries.

USB ports in ordinary lanterns serve only for charging batteries

A little strange to see the "cart with a jet engine", but, agree, it is convenient - the same flashlight can be charged with the standard cable from any PC, the delibera or charger with the corresponding socket.

Separately, you should mention the micro version 3.0 interface. Sockets and forks in it are somewhat different from connectors 1.0 and 2.0:

USB 3.0 cables - ordinary, mini and micro

Compatibility of versions

Since the interface specifications appeared almost one after another, the compatibility problem was quite acute and the designers looked at the "excellent" with this task. Everything three versions of the specification are fully compatible. According to the protocol "bottom up". That is, users of old interfaces could be allowed their gadgets with newer developments. In this case, the recognition of the very slow device on the network is performed by the ports automatically and does not require any action from the user.

As for the interface (pinout, shape of the nests and plugs), the first and second versions are compatible with each other completely. The version 3.0 is compatible with previous ones only by type normal USB"And" mini usb ". The micro USB connector of the third version insert in the nests of the previous ones will not be possible, but on the contrary - please.

Using the port for power and charging

In addition to transferring information, ports are capable of feeding external devices. To do this, in all modifications of the sockets there are two separate contacts (PIN). It is convenient for working with external devices that do not have its own power source - flash memory, keyboard, radio modules, etc. This is the property of the interface, as mentioned above, is often used in very non-computership gadgets.

It is curious that, depending on the task, the interface can be powered by the external devices and receive. If you, for example, connect the tablet to the panibank, the device will start charging your own battery. Connect to the same tablet flash drive or mouse, and the current direction will change - gadget will serve on the peripheral device. But if you switch the power to the user, the user does not need - all this is done automatically - then you need to know the load capacity of the ports. What current can you give a nest?

According to the specification, maximum currents for versions 1.0, 2.0 and 3.0 are respectively equal to 500, 500 and 900 mA. Nevertheless, not all gadgets are able to give such a current, and some can give and more. Everything will depend on specific device and its work. How to determine whether "pulls", for example, tablet external storage Or will the tablet connected to the PC be charged?

Of course, this information is in the accompanying documentation for each decent device, but you can use the "tyk method". USB is a universal port and smart enough. After connecting the devices, they divide priorities among themselves and disassembled, and how much it is necessary to each of them.

If the tablet is not able to provide a normal current, say, an external disk drive, the peripheral device will simply not turn on. If the PC does not have enough strength to charge the energy-intensive tablet full currentAnd the latter does not want to be content with small, the charging will not be carried out. Squeezing the ports equipped with overload protection, reverses and KZ to you in any case, such experiments will not be possible.

Theoretically, the third version interface sAMSUNG smartphone Designed for a current of 900 mA, but most likely, the gadget itself is not so much

Interface cable device

Well, so that the picture in the USB ports is complete, it is necessary to consider the wiring and purpose of each type of contacts. This information will be useful not only to programmers and "self-timeline", repairing interface cables and replacing broken connectors in gadgets, but also by simple users who wish to know what.

Pinout nests and plugs

Due to the fact that one of the main tasks in front of developers was the possibility of compatibility, the pinout and the location of the contacts of the sockets and the forks of all types in a small exception is different from one another.

Scheme of connecting contacts on a fork and a power outlet USB 1.0, 2.0, where: 6 - STDA_SSTX-;

7 - STDA_SSTX +;

8 - GND_DRAIN;

9 - STDA_SSRX-;

10 - STDA_SSRX +.

Color marking conductors

When placing cables, each of the connector contacts is assigned its color. It helps to avoid confusion in manufacturing and facilitates repairs. Standard Wiring Coloring in USB Cable Next:

• 1 - red;
• 2 - white;
• 3 - green;
• 4 - black (white for micro 3.0);
• 5 - black;
• 6 - blue;
• 7 - yellow;
• 8 - white;
• 9 - purple;
• 10 - brown.

Cable selection criteria

If you need to connect two devices via the USB interface, and there is no suitable cable, then it will have to buy it. But how to choose from all over the above diversity what you need? The choice criterion is extremely simple - if the cable plugs enter the device sockets, then you are in your hands what you need. The only thing that is worth remembering is: If you are using a version 2.0 cable for connecting devices with 3.0 jacks, then these devices will switch to the 2.0 protocol, but will work perfectly. And one moment. If at least one of the devices does not support Protocol 3.0, it makes no sense to buy a very expensive "Troychnaya" cable - you can do the usual for the second version.

The laptop has a jack of version 2.0, which means that whatever the cable you have connected these devices, they will work on the 2.0 protocol

Well, buying a cable, ask the interface, and not for charging. Some too smart producers save and make two-wire YUSB cables for charging, soldering only the power bus. With the form they can be exactly the same as ordinary interface, but are much cheaper, because they do not have wires for transmitting information.

The rapid development of computer technologies affects not only the main components of the systems. Increases the possibilities, including various interfaces. As for the most common method of connecting peripheral devices, - USB, - here in general, you can state a multiple increase in productivity in recent years. The capacity of the universal serial tire increases, the functionality is expanding. Changes are also subject to connectors used to connect a variety of USB devices. Today, many USB hearing is that the advantages and disadvantages of the solution are the topic of this article.

Connectors of a modern computer

Having looked around the body of almost any laptop, you can detect a number of different ports located on the sides. Among them is necessarily there is a USB, almost always HDMI and some others. Modern models are often equipped with the latest USB Type-C port. What is this connector, many do not know, but it would be worth familiar with the capabilities of the port. Presumably, the connector in the future will replace many other solutions and will become really universal standard. This is facilitated by the technical characteristics of the new method of interfacing the computer and the periphery. USB Type-C port offers users an enhanced data exchange rate, improved functionality, and new level Easy use. In short, the future of the standard looks very promising.

Many applications of one cable

Creators USB Type-C used when developing the standard very simple idea. The user must have a single cable type, and its computer equipment is equipped with one port type. Through the use of a unified interface, the connection is available all anything. For example using uSB cable Type-C can be connected inherently. different devicesrepresented by hard disks, monitors, audio interfaces, smartphones, tablet PCs. Among other things, it is possible to use the connector under consideration even for charging the laptop.

USB-A.

To date, almost all peripheral devices are connected to a PC through the usable USB-A connector. This port firmly entered the computer world, has a familiar rectangular shape, and its use has become practically a standard for pairing with PC and laptops flash drives, external keyboards, mice, hard disksPrinters and many other devices. Such a monopoly is likely to soon be destroyed - the USB cable Type-C is already a worthy place among the solutions used to connect a set of devices.

Change concept

To connect devices to the long-standing standard USB-A port, various cables are used. The main difference between them is the connector located on the opposite, the cable side connected to the computer. It is almost always another type of connector. For example, Micro-USB is used for smartphones, MINI-USB is often used for other gadgets. To connect the printer, you will need a cable with a USB-B connector, and to connect storage devices - Micro-USB-B. Such a variety causes some inconvenience and difficulties, because the user who owns several devices always needs to have a whole set of cables at hand. Called to be one for all devices, i.e., a universal USB cable Type-C repeatedly simplifies this situation.

New format

With the development of the standard, it was possible to establish a single design of the connector for all devices, as well as the same connector at both ends of the cable. How to understand by taking a USB Type-C cable, what exactly is he? The solution is a subtle connector having an oval shape and significantly smaller in size in comparison with previous cable formats and connectors of this type. In addition, USB 3 Type-C received the most important characteristicrepresented by symmetry and reversibility. In general, it is very similar to the solution of Lightning from apple companies - Very convenient, because you do not need to spend time on manipulation with the cable to find a sure way of connecting.

Future

Probably today it can be argued that after a certain time, the USB connector Type-C will turn into a single universal port for all peripheral devices. Thus, there will be a replacement of USB-A, B, Micro-USB and MINI, so complicating the life of ordinary users today. All cables should be the same and have the ability to use for any devices. Of course, rapid unification will not happen, too many workable devices with different from USB Type-with connectors are used today and will be operated for several more years.

At the same time, you should not forget: the expansion of new solutions has already begun. For example, USB Type-C flash drive is not at all uncommon on the shelves of computer stores. In addition, the fact of the exit of flagship devices from the most famous brandsThe port in question, suggests that the situation described, i.e., the outstanding of obsolete connectors from the market sooner or later will come. For compatibility with old solutions, so far you have to use a USB Type-C adapter.

Compatibility

After reading the foregoing, you can think about what to do with already acquired devices equipped with connector types other than USB Type-s. It must be said that this question should not cause special concern. Already designed, produced and sold the most diverse adapters, allowing you to connect any devices with a USB connector, regardless of its type. MINI-USB type adapters - Type-C, Micro-USB - Type-C and others are already widespread and perfectly perform their functions. The principle of providing applied in computer technician for many years, no one is going to violate. If there is a USB Type-c port or computer, the adapter for other types of connector is quite applicable and effective solution.

Read more about the advantages of the connector

Of course, a simple revision of the construct that the connector was undergone and the port will not be a significant reason for the expression of the user to the upgrade of the entire periphery, but the execution is far from the only advantage of a new solution. The new format is supported by the most modern USB protocol 3.1, carrying an increase in the rate of data exchange and greater versatility in comparison with previous versionswhich are used on devices equipped with USB-A.

Speed

Since the presentation of the first version of the plumbing has already passed more than two decades. At that time, the maximum speed with which the data was transmitted was 12 MB / s. To date, it can be argued by considering USBType-C that this is the most fast interface To connect peripheral devices from existing solutions. The USB 3.1 standard is capable of providing a data rate of 10 GB / s.

Performance

Additional advantages of the standard under consideration, of course, include the performance provided by the ability to transmit power to 100 W. This indicator is enough to provide the energy of almost any laptop, not to mention smartphones, tablets and other gadgets. In addition to energy, the new format supports the transfer of a huge amount of data per unit of time. For example, today via USB Type-with successfully transmit a video signal in a resolution of 4k.

Universality

Universal nature the newest Standard A wide range of practical applications opens. Mass useful features You can provide using a single cable. For example, you can connect the equipped USB-C laptop To the monitor with external power and charge the laptop battery, while simultaneously browsing the video content. In the case when storage devices are connected to the display, for example, external disk, From the laptop you can access the stored information on the media.

USB Type-C Disadvantages

This connector is a brilliant new format, without a doubt that applying the title of the ubiquitous decision in the very near future. At the same time, the initial stages of distribution and development, on which this moment Still there is a standard, do not ensure the complete absence of dangers, as well as some confusion when using the connector.

Cheap accessories

The main problem with which the user may encounter, having decided to join modern trends, are cheap low-quality accessories and cables. In view of large number The energy transmitted through USB Type-C connectors, the use of insufficient quality cables can damage the mating devices. This factor must be taken into account by users in obligatory. When buying cables and adapters, you should choose products of reliable proven brands.

Confusion in standards

Another unpleasant moment with which users of USB Type-C may be encountered today caused by the fact that the standard under consideration relates more to the type of connector used, rather than to the specifications of the interface itself. Therefore, the situation in which the device connected to a new connector will work not as fast as the debt owner expected. The first generation uses USB 3.0 technology, providing a maximum speed of 5 GB / s. The second generation of USB-C is supported by Standard 3.1, the data transfer rate through which is already reaches 10 GB / s. Problems with each port arise due to the fact that they look equally, but in the manufacture of ready-made solutions, various components are used by brands even in lineups of similar models. In other words, before buying a device with a USB Type-C connector, you must check the matches of real technical characteristics Port Required Indicators.

This material is suitable for beginners and professionals. Some often concerns the question of how to determine the type of USB port. This is especially the difficulty when in the laptop all ports are marked with black, although the characteristics say that USB 3.0 and 2.0 are present. The truth is not written from which side.

This article will not only help determine USB 3.0, but also try to distinguish the fake. The article will be small, but will fully help figure out what.

Determine the view of the USB port using Windows

Now I will try to show everything programmatically, and then look at the ports themselves. Most of you know that USB ports have versions 1.0 , 2.0 and 3.0 . Now there is already version 3.1, but it does not matter. To determine the type of USB port, you need to go to the Device Manager. In Windows 10 click right-click mouse on the launch menu and choose the corresponding item (or press the combination Win + X. And do the same).

As soon as the window has been opened by the tab "USB Controllers" And reveal it. There we can see many drivers for USB ports. If one of the devices have a word "Xhci"This is USB 3.0, everything else belongs to USB 2.0.

Easily? Then we turn to the next variant of the definition.

How to determine the type USB port in appearance?

Let's start with the first version - USB 1.0, now this option in laptops is practically not used, but takes place in some mice and other devices. It looks like this:white Port S. 4th contacts - This is USB 1.0.

USB 2.0 usually painted in black And inside also has 4 contacts. The second type is compatible with USB 1.0, but differ only by bandwidth. The second type is faster.

In this example, we looked at the flash drive, but what does the connector look like, for example, in a laptop?That looks like:

Almost no different. Important moment - Some manufacturers can paint the same USB 2.0 to another color, for example, orange. Of course, it does not affect the interface characteristics.

USB 3.0 looks like blue Port and it has 9 contacts. Four are ahead, the remaining five from behind. See careful. Those that behind a little raised. If the material is blue, then this is exactly USB 3.0. Also, on some computers next to the connector you can see the inscription "SS"What does the maximum data transmission rate (Super Speed).

Sometimes you can see USB 2.0, which is also blue, and how to understand it? As I said, developers can use any design. Determine the USB type you can by number of contacts.

I would like to note that USB 1.0, 2.0 and 3.0 are compatible with each other, so you can safely use them as it looks like. For example, insert a USB 2.0 connector to 3.0, though the speed will be at 2.0.

So, let's summarize, now I once again we will describe the features of USB ports:

USB 1.0.

• White material;
• It has 4 contacts.

USB 2.0

• Made of black or blue material. Depending on the preferences of the developers, there may be any other color;
• It has 4 contacts.

USB 3.0.

• The material is almost always blue, but also occurs black;
• Always 9 contacts - 4 ahead and 5 rear.

That's all I wanted to tell about the definition of the type of USB ports.
