How to install drivers if usb does not work. USB ports on the computer do not work - ways to solve the problem
This happens when USB ports on the computer stop working. In this article we will look at common reasons that lead to such a problem, and solutions. The very first thing you can do is restart your computer, since common problems with USB ports are due to an error in the driver. If this method does not help, move on.
Perhaps the settings in the BIOS have gone wrong motherboard. If the corresponding USB controller is disabled for some reason, it must be enabled. When you start the computer, press the Del or F2 key to enter the BIOS. Next, in the Integrated Peripherals or Advanced section, we will find a similar item on the USB Controller and see what position it is in (Enabled - enabled, Disabled - disabled). So, if you have the Disabled mode set, change it to the opposite. To save the changes, press the F10 key and agree by pressing YES. After the reboot, the ports should work, if that doesn’t help, then follow the steps below.
Reasons why USB ports on a PC do not work:
- Any faulty USB devices A: I recommend turning on the computer, having first disconnected everything (mouse, keyboard, printer, webcam, etc.). Leave only one working flash drive. If the flash drive starts working when you start the computer, then the peripheral devices are to blame. You can determine which one is faulty by connecting it to the computer one by one.
- ports may not work due to faulty software code. Go to the “Task Manager”.
Look carefully in the “USB Serial Bus Controllers” section if you have a device with exclamation mark, then this indicates that it is not working properly. Double click mouse to open it, and in the window you can read information about the fault.
- Alternatively, you can remove all controllers responsible for USB, and then reboot the system. After launch, Windows will automatically install them again. After this, it is likely that the USB ports will work.
- If the problem with the ports is due to a failure in program code, then you can try to restore the operating system, that is, roll it back to the latest control point. Go to the Start menu - Control Panel. Here we find the “Recovery” section.
Next, click the “Start System Restore” button. A recovery window will open and following the prompts you can roll back the system.
- Also, a similar problem may occur due to the lack of a driver for the motherboard chipset. In this case, you need to enter this data on the manufacturer’s website. After downloading and installing the driver, you should restart your computer.
- To make sure the problem is in the system or hardware, you can boot from any Live CD. If after booting from such a disk/flash drive the ports work, then the problem is clearly in the operating system and there is only one way out - reinstall Windows. If in virtual system USB doesn't work, then the problem is in the hardware. In this case, we do what is written below.
There was a case with one friend when they stopped working usb ports. Replacing the 3-volt battery on the motherboard solved this problem.
- Alternatively, you can update the BIOS. This solution helps many users. To update the BIOS, go to the official website of your motherboard manufacturer and in the “Download” section, find the latest BIOS version. There you will find detailed instructions by update.
- If you experience frequent problems with USB ports, I recommend installing a PCI-USB controller. A good thing that will be independent of your built-in ports.
- The last option is to have your PC repaired, where professionals will probably make an accurate diagnosis.
That's all, friends! Thank you for your attention!
USB (Universal Serial Bus or Universal Serial Bus)- the most multifunctional port to date. Using this connector, you can connect not only a flash drive, keyboard or mouse to your computer, but also many other devices. For example, there are portable mini-fridges with USB connection, lamps, speakers, microphones, headphones, mobile phones, video cameras, office equipment etc. The list is actually huge. But in order for all this peripherals to work properly and data to be transferred quickly through this port, it is necessary to install drivers for USB. In this article we will look at an example of how to do this correctly.
By default, USB drivers are installed along with the motherboard software, as they relate directly to it. Therefore, if for some reason you do not have USB drivers installed, we will turn first to the websites of motherboard manufacturers. But first things first.
In the case of USB, as with any other computer components, there are several ways to find and download necessary drivers. Let's look at them in detail in order.
Method 1: From the motherboard manufacturer's website
First we need to find out the manufacturer and model of the motherboard. To do this, you need to follow a few simple steps.
- On the button "Start" you need to right-click and select « Command line» or "Command Prompt (Administrator)".
- If you have an operating system installed Windows system 7 or below, you need to press the keyboard shortcut "Win+R". As a result, a window will open in which you need to enter the command "cmd" and press the button "OK".
- In both the first and second cases, a window will appear on the screen "Command line". Next, we need to enter the following commands in this window in order to find out the manufacturer and model of the motherboard.
- Now, knowing the brand and model of the motherboard, you need to go to the manufacturer’s official website. You can easily find it through any search engine. For example, in our case it is ASUS company. Let's go to .
- You need to find a search bar on the site. We enter the motherboard model into it. Please note that in laptops, most often the motherboard model matches the model of the laptop itself.
- Pressing the button "Enter", you will be taken to the search results page. Find your motherboard or laptop in the list. Click on the link by clicking on the title.
- In most cases, you will see several sub-items at the top. mother card or laptop. We need the line "Support". We click on it.
- On next page we need to find a point .
- As a result, we will be taken to a page with a selection of the operating system and the corresponding drivers. Please note that you may not always be able to see the required driver on the list. In our case, the driver for USB can be found in the section "Windows 7 64bit".
- Opening the tree "USB", you will see one or more links to download the driver. In our case, select the first one and press the button "Global".
- The download of the archive with installation files will begin immediately. After the download process is complete, you need to unpack all the contents of the archive. IN in this case it contains 3 files. Run the file "Setup".
- The unpacking process will begin. installation files, after which the installation program itself will start. In the first window, to continue, you must click the button "Next".
- The next point will be to familiarize yourself with license agreement. We do this as desired, after which we put a mark opposite the line "I accept the terms in the license agreement" and press the button "Next".
- The driver installation process will begin. You can see your progress in the next window.
- Once the installation is complete, you will see a success message. To complete you just need to press the button "Finish".

This completes the process of installing the USB driver from the manufacturer’s website.
Method 2: Using automatic driver update programs
If you don’t want to bother with searching for the manufacturer and model of the motherboard, downloading archives, etc., then you should use this method. For this method, you will need any utility to automatically scan the system and download the necessary drivers.
For example, you can use or . In any case, you will have plenty to choose from. Similar programs on the Internet today large number. Take for example the same one. ABOUT detailed installation You can learn about drivers using this program from our special lesson.
Method 2: Through Device Manager
Go to Device Manager. To do this you need to do the following.

Please note that this method is the least effective of all three. But in some cases it actually helps the system to at least recognize the USB ports. After such an installation, you need to search for drivers using one of the two methods listed above in order to ensure that the data transfer speed through the port is as high as possible.
As we previously advised, for any force majeure situations, always save the most important and necessary drivers and utilities on a separate medium. If necessary, it can save you a lot of time, which will be spent searching for software again. In addition, situations may arise when you simply do not have access to the Internet, and you will need to install drivers.
USB technology is one of the most important of the many technologies that have had a huge impact in computer world. USB (Universal Serial Bus- “universal serial bus”) - serial interface data transfer for low- and medium-speed computer peripherals
This technology has made it truly easy and convenient work with printers, scanners and external devices data storage (external hard drives, USB flash drives). All actions with USB installation devices have been reduced to 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 maximum speed transfers up to 5.0 Gbit/s. 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 USB connectors, as well as devices with external damage to the housing or with a clear burning smell.
If on the mother USB board Since the ports are mechanically damaged, it is better to disconnect them from the motherboard (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 strive 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's always safer to buy an additional PCI or PCIe USB controller than working 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 desktop computer, installation additional USB The controller is a very expensive pleasure.
In many cases, when the error message " USB device not recognized "The problem may be precisely 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 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 most in a simple way The solution to this sudden problem will be to restart your 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 you restart your computer in at the moment is not desirable (for example, due to performing some important operation), 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 make it work USB ports- disconnect 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.
Update USB drivers-controllers
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 is damaged, in particular south bridge motherboard. In this case, the best thing you can do is replace or repair the USB port controller at a service center.
Typically, USB drivers are installed along with the operating system. If you need to install them yourself, keep in mind that it is best to download them directly from the manufacturer’s website.
This process is described in more detail in the article on how to find latest versions drivers. Be sure to keep in mind that for usb they should be provided free of charge; if you are offered to buy, this should immediately alert you.
Moreover, they are constantly updated, as a result of which those posted on unofficial websites of manufacturers are most often outdated.
In this article I will describe how to install or update drivers for usb in the simplest (effective) way.
To do this, you will need to open the device manager. Click start as shown in the picture (bottom right) and paste Devmgmt.msc there.
A utility will appear at the very top - click on it.
In the window that opens (look at the figure), find “usb controllers” and by clicking on the small black triangle on the left side, expand the menu (see figure)
Continue to select the controller you need, click on it, select “properties” at the bottom and you will find out everything you need.
Also, right there, if you wish, you can easily update all the drivers for computer usb or laptop.
As you can see, in order to install the usb drivers you need, you will need to find out the manufacturer, after that you can go to their website (or update directly in the manager), enter required parameters and find him.
Depending on the manufacturers, sites may vary. Sometimes drivers for usb can be found through a search, sometimes there are installed scripts, which they themselves will find, and sometimes just choose from those provided.
If you need drivers for usb Intel, then go to
Http://www.intel.com/p/ru_RU/support/
Find there " automatic check computer", install the provided script, and the system will independently check your PC and show that it needs to be updated.
Very useful and effective method. There are other ways, for example, go to the site: “driver.ru/?C=48” and try to find drivers for usb there.
Yes, there are a huge number of them, thousands of users constantly go there and download them.
But I don’t really like this method; I always look on the official websites of manufacturers. That's where the most best drivers for usb.
