• How to find out the version of the USB port. How to find out which USB

    You, of course, know that the USB 3.0 interface works much faster than 2.0. Its maximum throughput is almost 10 times greater than that of the “two”. In order to fully experience the benefits of a high-speed interface, it is necessary that it is supported and removable media, and a computer. Let's look at how to distinguish computer ports USB 2.0 and USB 3.0.

    First of all, you should pay attention to the year of manufacture of your computer (motherboard). If your device was released before 2010, USB 3.0 will not be found on it.

    You can distinguish the type of USB ports by visual inspection:

    Front panels desktop computers, as a rule, are equipped with additional USB ports. However, we do not recommend connecting flash drives to them, since budget motherboards only support USB 2.0 for additional ports.

    How to check the type of USB ports in Windows

    Define type installed port possible using system Windows tools. Launch from Device Manager, find the section “ USB controllers" and unfold it. If your computer has USB 2.0 ports, then the list of Enhanced Host Controllers will not contain devices with “USB 3.0” in their names.

    If your computer has USB 3.0 ports, the names of the advanced controllers will clearly indicate “USB 3.0”.

    How to add USB 3.0 ports

    If your computer does not support the “troika”, you can do without upgrading the motherboard. Try an alternative solution - a USB 3.0 adapter. This device exists in several versions:

    • Slot board PCI Express, an excellent solution for a desktop PC;
    • Adapter for ExpressCard, laptop version.

    Instead of an afterword

    We have discussed with you how you can quickly distinguish the type of USB ports installed in your computer. We hope that now you won’t languish for a long time waiting for data to be written to a flash drive, external hard drive or other drive.

    Universal Serial Bus is a serial universal bus. It was developed as an alternative to parallel and serial data transfer protocols. In January 1996, standard 1.0 came into force. A lot of time passed before the USB 2.0 standard was released.

    What is the usb speed

    In general, for a universal bus four various types data transfer rates. They should not be confused with versions of USB itself. Improved data transfer rates have been introduced in each subsequent version of the USB standard, of course, with support for all previous ones. It is necessary to take into account that Universal Serial Bus version 2.0 devices do not always provide data transfer at High-Speed ​​speeds. Full-Speed ​​is the level where maximum speed remains only for some devices. Next version USB standard is 3.0. It supports not only SuperSpeed, but also the three previous speed types. It also references version 2.0 rather than replacing it. High-Speed ​​cannot be defined as a version of the 3.0 standard because devices such as Full-Speed, Low-Speed, and High-Speed ​​are classified as USB standard 2.0, but not USB 3.0.

    How to determine which usb

    USB-IF (USB Implementers Forum) has developed a special logo for each speed type. It can be used to determine the correspondence between a device and a standard.

    device Manager Windows systems- This Device Manager. It will help us find out whether a device of a certain speed supports any specific device USB. In general, it is believed that this is not the most suitable solution to the problem. We will need to try different USB root hubs to find required device. But how do you know which USB?

    First, let's open Device Manager. To do this, point the mouse at the “My Computer” menu. Right-click on the line "Properties" - "Hardware" and "Device Manager". Next, we need to expand the “Universal Serial Bus Controllers” node and open a window with the properties of the USB root hub. To make it convenient for us to work, let's start from the bottom. The next step is to go to the “Power” or Power tab.

    If our device is connected to this hub, then we will be able to notice that it will appear in the “Connected Devices” or Attached Devices section. Also note that the root USB has exactly six ports. One of them is used by the device.

    To find out the speed of the Universal Serial Bus, we need to open the “Advanced” or Advanced tab. Root hubs can operate at multiple speeds simultaneously.

    Every desktop computer, laptop, tablet and any other gadget has USB ports. If port speed is not important for devices such as a keyboard and mouse, then for the operation of removable flash drives hard drives and cameras it is one of important indicators. If the port is slow, then transferring files from one device to another takes a long time. To correct this situation, you need to know some features of USB ports.

    USB port specifications

    Today there are three types of USB ports:

    • USB 1.1;
    • USB 2.0;
    • USB 3.0 (3.1).

    The speed of their work is different. In this case, you need to take into account the speed of connected devices, which also have their own parameters. For example, if you have a flash drive with USB connector 3.0, and the computer has USB 2.0 ports. The flash drive will not work faster than the speed stated for port 2.0. This technical features devices that can only be changed by replacing the PCI controller.

    As for technical characteristics USB ports 1.0 and 1.1, then they are as follows:

    • Two modes of information transmission, namely with high throughput at 12 Mbit/s and low – 1.5 Mbit/s.
    • Maximum length cable for data transmission in high-bandwidth mode is 3 m. For low-bandwidth mode – 5 m.
    • The maximum number of connected devices is 127.
    • It is possible to connect a device that operates in modes with different bandwidths.
    • Voltage for peripheral devices– 5 V.
    • Maximum current – ​​500 mA.

    The USB 2.0 port differs from its predecessor in the following parameters:

    • Implemented HiSpeed ​​mode 480 Mbit/s.
    • Speed ​​for interactive devices is 10-1500 Kbps.
    • Speed ​​for video and audio devices is 12 Mbit/s.

    USB 3.0 (3.1) port on at the moment is the most popular and fastest. Among the advantages of this port worth highlighting:

    • Data transfer speed is up to 5 Gbit/s.
    • The controller is capable of sending and receiving data simultaneously. In this case, data exchange does not affect the speed of the port.
    • Has more high strength current, which allows you to connect external hard drives to your PC, mobile devices, and even monitors.
    • Well compatible with UBS 1.0 and 2.0 standards.

    How can I check which port is installed on my computer?

    The first and easiest way to find out your USB port type is to look in the documentation for your PC. However, if you don’t have it, follow these steps:

    • Download the AIDA, Everest or any other program. We will use the first software. Launch AIDA on your PC.
    • In the menu, select “Devices”, select “USB devices”. A list of USB ports will appear in the right menu.

    • Thus, we have established the number and type of ports that are available on our device.

    Ways to solve the problem with slow USB ports

    If your PC supports USB port 2.0 and you connect a medium with the same bus type to it, but the data transfer speed is negligible, it’s worth checking BIOS settings. Often the maximum speed for ports may be disabled in BIOSe. To check this parameter, perform the following steps:

    • We reboot the PC and exit into the BIOS by pressing “Del” and “F2” (the login buttons are different for each motherboard model).
    • Go to the “Advanced” section (depending on the motherboard model, it may be different) and look for the “USB Controller” setting. Select the port and set it to “FullSpeed” or “HiSpeed”.

    • Save the result with the “F10” button and boot in normal mode.

    If your PC does not have a USB 2.0 port or you want to add 3.0, you will need to buy a special PCI USB 2.0 or 3.0 controller. Such boards are relatively inexpensive. You can install the controller yourself. To do this, you should perform the following steps:

    • Turn off the PC;
    • Opening the side cover system unit;
    • We connect the board to the PCI slot. We fix the board to the front or rear panel of the PC using a screw.
    • Turn on the PC and install drivers for the new component.

    It is also worth noting that low speed Port malfunction may be caused by damaged or missing drivers. In this case, a message may appear: “This device may run faster...”. To fix this situation, you need to update your drivers. You can do this through the device manager by right-clicking on the controller, which is displayed with a yellow exclamation mark, and selecting “Update driver.”

    After rebooting your PC and reconnecting, the problem will be fixed, unless you connected USB flash drive 3.0 to USB 2.0 port.

    Finally, it is worth noting important point. When copying small files, the data transfer speed is significantly reduced. This is due to the search for a free block on the disk for each file. To speed up copying, it is worth compressing these small files into one archive in advance.

    How to find out if your computer has USB 2.0 or 3.0 ports

    The USB 3.0 interface is significantly more productive than its predecessor, USB 2.0. While the latter limits the speed linear recording data on a flash drive with an indicator of 30-40 MB/s; through the first, files can be copied to a USB 3.0 flash drive at a speed of about 100 MB/s. This real example, in theory, the maximum throughput of USB 2.0 is 60 Mb/s, and USB 3.0 is 625 Mb/s. To take advantage of the USB 3.0 interface, both the storage device (flash drive, USB-HDD, other storage devices) and the computer must be equipped with it. How do you know if your computer has USB 2.0 or 3.0 ports?

    Laptops and PC motherboards released before 2010 are likely to have USB 2.0 ports installed. But computer devices, released later may be equipped with USB 3.0.

    You can find out which USB interface your computer is equipped with by the external features of the ports. USB 1.0 ports have 4 pins and plastic underneath white. USB 2.0 ports also have 4 pins, but the plastic underneath is usually black. There are as many as 9 pins inside a USB 3.0 port, and the plastic underneath is usually blue. Latest models PCs and laptops can be equipped with the most powerful USB 3.1 interface to date with a stated maximum throughput of 1250 Mb/s. The plastic under the contacts of such ports can be painted either black or blue. What distinguishes USB 3.1 ports from their predecessor interfaces is the inscription “SS” (Super Speed) engraved next to them.

    PC cases usually come with a panel on the front with additional USB ports for easy connection of devices. But for such convenience, computer owners who do not know that their motherboards support USB 3.0 often pay with agonizing wait while moving data to a flash drive. After all, even modern but budget cases are usually equipped with USB 2.0 ports.

    You can find out whether your computer has USB 2.0 or 3.0 ports using Windows tools. Go to the device manager and open the “USB controllers” branch. If in the list of the branch the host controllers are listed as “Enhanced Host Controller”, and their names do not contain the addition “USB 3.0”, this means that the computer has USB 2.0 ports.

    The presence of USB 3.0 ports will be directly indicated by the addition “USB 3.0” in the names of extended host controllers. The fact that the computer supports USB 3.0 is also evidenced by the presence in the list of a branch of controllers, the name of which contains the abbreviation XHCI - an indication of the universal eXtensible Host Controller Interface.

    How to get USB 3.0 ports if they are not found? A total upgrade in the form of replacing a laptop or PC motherboard with all its dependent components has an alternative - installing a USB 3.0 adapter. For PC assemblies, such adapters exist in the form of boards installed in PCI slot Express. To laptops USB adapters 3.0 are connected using an ExpressCard slot. On AliExpress, USB 3.0 adapters can be ordered for a promotional price of just over $5. This option will give a certain increase in productivity, but still will not reach USB capabilities 3.0, natively supported by modern laptops and motherboards. After all, data transfer will be limited by the bandwidth of the corresponding slot.

    What to do if the USB port does not work

    There are times when, after connecting a device via a USB port, a computer, or simply applications begin to work incorrectly. The reasons for such a failure may be different. Before identifying the problem, you need to check the functionality of the unit itself, the USB port and the driver. Let's look at several ways to help resolve this problem yourself. Rebooting the system Quite often this helps resolve the issue.

    Sometimes it’s worth doing the following: turn off the computer and disconnect everything connected via USB, including the keyboard and mouse. Then turn it on and then full load the operating system, in the next order, return everything back to its place. If, after connecting, for example, a mouse, some trouble arose, then remember which input it happened on. Connect it again to a different port. If the problem does not occur, then this one is faulty. Otherwise, the point is in the mouse or cable itself.

    Connector and USB cable

    Quite often the cause of inoperability is a damaged connector or cable. It is worth carefully inspecting these elements to see if there is any damage on them (cracks, cuts, chips). Is there any dust, small objects, or other contaminants inside the connector? Connectors can be cleaned using a brush or air compressor, such as a vacuum cleaner. The cable must be disconnected during cleaning. If the interface cord is broken or too bent, then it needs to be replaced - this process is absolutely not expensive.

    What is causing the problem - the device or the port

    If normal functioning computer or application starts after connecting the device to USB, then you need to try connecting another unit to the same port. If the device works fine, then the problem is most likely in the device itself. Also try connecting the same device to another to check its functionality. If problems begin on another PC, then it needs to be replaced. If a USB hub is used, then it must be excluded from the connection circuit - if problems arise, the device must be connected only directly. In addition, problems may occur due to simultaneous connection large quantity peripherals or devices of the same models (two printers, two phones).

    Reinstalling the driver

    If the system has detected a problem with the driver, the user is given a message about this problem. In this case, you need to do the following: click “Start - Control Panel - Device Manager”. On the list installed equipment There is a subsection “USB Controllers” (“Universal USB Bus Controllers”). By expanding this section, you will see an item in the list of USB devices marked with an exclamation mark on a yellow background. Click the right mouse button on it and context menu select “Delete”. Next, simply restart your PC. After downloading operating system will automatically reinstall the driver that was removed. If this reinstallation of the driver does not help, you should try updating it. Using the method described above, go to “Device Manager” and in the “USB Controllers” section, find the problematic port. Double-click on it with the left mouse button and in the dialog box that opens, find the “Driver” tab. In this tab you need to click the “Update” button. After updating the drivers, you need to reboot the system.

    How to disable USB ports

    Many modern computer peripherals, such as external hard drives, mobile phones, keyboards, video cameras, are connected via a USB cable. Depending on your computer, it may have USB 1.0 or USB 1.1 installed, or more modern versions USB 2.0 and USB 3.0, which are significantly faster, improving the performance of your devices.

    Instructions

    Click the "Start" button. Right-click on "My Computer" and select "Properties" from the drop-down menu.

    In the window that appears, select the “Hardware” tab and then “Device Manager”. Click on "Universal Serial Bus Controllers".

    Look for the word "extended" in the USB port description. If you see this word, it means a USB 2.0 port; if you couldn’t find one, it’s a port version 1.0 or 1.1. If you see an entry called "xHCI" - the USB port is version 3.0. may also contain the inscription "USB 3.0"

    Another way to determine whether your computer uses a USB 3.0 port is to look closely at the USB cable. Connector USB cable 3.0 has additional pins.
