USB technology is one of the most important of the many technologies that have made a huge impact in the computer world. USB (Universal Serial Bus- “universal serial bus”) - a serial data transfer interface for low- and medium-speed computer peripheral devices
This technology has made it truly easy and convenient to work with printers, scanners and external storage devices (external hard drives, USB flash drives). All actions with installing USB devices came down to a simple principle: “ Plug and play" Devices have become truly mobile precisely because of USB technology. Today, not only desktop PCs and laptops are equipped with USB ports, but also gaming devices, smartphones, cameras, navigators and many other devices.
Ports USB version 2.0 provide data transfer at speeds up to 480 Mbit/s, and the version USB 3.0 raises the maximum transfer speed to 5.0 Gbps. The USB symbol is a kind of trident, drawn both on USB devices and on computer connectors.
USB technology has already been studied quite seriously and has undergone many improvements, so USB ports, when used correctly, rarely cause any problems, and troubleshooting problems associated with them does not cause much trouble. This article will outline the basic principles of troubleshooting USB ports.
But before we begin, it’s worth describing basic recommendations when working with USB ports and devices, connected to them:
- never connect devices with visible mechanical damage to USB connectors, as well as devices with external damage to the case or with a clear burning smell.
If the USB ports on the motherboard are mechanically damaged, it is better to disconnect them from the motherboard (the connectors on the front of the case) or seal them with colored tape to prevent their use. If necessary, it is better to replace such ports in a workshop with new ones.
Try not to overload USB ports. Their current strength is strictly limited: 500 mA for USB 2.0 and 900 mA for version 3.0. Do not try to increase the number of USB ports using various USB multipliers. Modern motherboards already have up to 10 ports, which is quite enough for home use. It is always safer to buy an additional PCI or PCIe USB controller than to work through a USB “tee”.
If the USB ports on a laptop stop working, then working on it becomes very difficult - you cannot connect a printer, a scanner, or a flash drive. And unlike a desktop computer, installing an additional USB controller is very expensive.
In many cases, when the error message " USB device not recognized "The problem may be in the USB port. This problem is usually solved quite easily, since it occurs mainly at the software level.
What to do if the USB ports do not work?
Any hardware device interacts with the installed operating system through a special program - driver. Many problems with devices are solved with the help of drivers. The same is the case with non-functional USB ports. Below are several methods that will help you troubleshoot USB ports at the software level.
If the USB ports suddenly stop working and USB devices are not detected, then the easiest way to fix this sudden problem is to restart the computer. Just restart your computer. If there were no problems loading the drivers, this problem will be resolved after a reboot.
Update hardware configuration in Device Manager
If restarting the computer is not desirable at the moment (for example, because some important operation is being performed), then you can “reload” the drivers without rebooting the entire computer via device Manager. To launch it on the shortcut " My computer» right-click and select the menu item « Management e". Or in the menu " Start» find the program « Execute"and after launching it, enter the command devmgmt.msc.
In the window that opens, left-click once on the list of devices and then click the tab " in the main menu Action", then point to " Update hardware configuration" See if the section " USB controllers" If yes, then your problem is solved, the USB ports should work.
Another way to get USB ports to work is to unplug and then reinstall the USB controller. To do this you need to run again device Manager. In the list of equipment that you will see in the window that opens, find the USB controllers section. On each of the devices in this section, right-click and delete them all. Once you remove all controllers, simply restart your computer. The controllers will be reinstalled and the USB ports will become available again. This may solve your problem.
Updating USB controller drivers
Another reason that USB ports do not work is damage to the USB controller drivers. The only way out is to find the correct drivers and reinstall them. To download the appropriate driver, you need to find out the manufacturer of the USB device port (via it). Installing the correct driver should solve this problem in an instant.
Disabling other USB devices
Sometimes USB ports do not work due to overload when too many USB devices are connected. USB hubs sometimes do not provide enough power to the devices connected to it. The connected device can consume all the permitted power of the computer's USB controllers. If the equipment is connected to a USB hub, then simply connect the device directly to a USB port on your computer.
You can also leave the device connected to the USB hub, but first disconnect other devices in the hub. For the future, purchase a USB hub with its own power supply that will provide sufficient power to all devices connected to it.
If none of the above methods worked, then it is likely that the USB ports were physically damaged. Or the USB controller, in particular the south bridge of the motherboard, is damaged. In this case, the best thing you can do is replace or repair the USB port controller at a service center.

Many users don’t even know that you can download a USB driver for Windows 10, and have been using their device for years without this driver. At the same time, there are cases when the USB port in the device works, but its speed could be higher if the user downloaded and installed the USB driver.
Peculiarities
For a USB port not to work at all - this rarely happens. But it still happens, in this case the thought of downloading a USB driver comes on its own, as a result it allows:- Set up the USB port;
- Increase data transfer speed;
Please note that our USB driver, which you can download on this page, will help you get the port working on your desktop computer, laptop, and even tablet. The version is compatible with Windows 10 64 bit, so the driver, unfortunately, will not work for 32-bit OSes.
If the USB ports on your computer have stopped working, then you need to download the USB driver and install it on your system. This will ensure proper operation of all connected devices and data transfer at maximum speed.
A problem may be indicated by the lack of any response from the connected device. In this case, you can go to the device manager and see a yellow exclamation mark next to the port with the inscription “Unknown USB Device”.
If you know exactly the model of your motherboard, you can find the USB Universal Serial Bus controller driver for it on the manufacturer's official website. Well, if this information is not available, then use the Driver Pack application. It will scan the system itself and find all devices that need driver updates, including USB inputs.
Check the boxes for those that need updating, and the program will do the rest for you. Reboot everything should work at its best.
