How to enable usb support in BIOS. How to properly enable usb ports in BIOS

You can enable USB ports on your laptop through the BIOS, Device Manager, Registry Editor, or Editor group policies. If access to the USB connectors was intentionally prohibited using special software, then you can unblock it in a program where the interface is blocked. All methods are available ordinary users and do not require special training.

Disabling unnecessary devices

If the USB ports suddenly stopped working and you are now looking for how to turn them on, then the first thing to do is see if the device is connected to the laptop a lot. When using a USB hub, the laptop may not be able to supply power to all devices, causing the USB ports to become unresponsive. Before you do USB setup in the BIOS, disconnect unnecessary equipment from the laptop and check if the ports work. If nothing has changed, then reboot the laptop and go into the BIOS.

Enabling ports in BIOS

For BIOS input When loading, press Delete, F2 or another key depending on the model motherboard. You can view it on the start screen.

In the case of a laptop, this screen does not appear because the fast boot feature is activated. You can temporarily disable this technology in the power settings:

Restart your computer. Without quick launch you will see all stages Windows boot and you can get into the BIOS. If this doesn't work on Windows 8 or 10 with UEFI BIOS, try the following method:

After reboot, select "Diagnostics", then go to " Additional options" and open the UEFI Firmware Settings. Click "Reboot", the next time you start, the BIOS UEFI interface will appear.

To configure USB ports in UEFI, you need to go to the “Peripherals” tab and set the “Legacy USB Support” parameter to “Enabled”. If support for USB 3.0 ports is required, activate the corresponding item (USB 3.0 Support).

In the AMI BIOS, go to the “Integrated Peripherals” section and set the value “Enabled” for four options:

• USB EHCI Controller.
• USB Mouse Support.
• USB Keyboard Support.
• Legacy USB Storage Detect.

In Phoenix AwardBIOS, you need to go to the “Advanced” tab and go to the “USB configuration” section. All parameters inside must be set to “Enabled” for the USB ports to work.

In all BIOS versions, to save the configuration, you must press the F10 key and confirm the selection by writing “Y”.

Windows setup

If in BIOS ports are enabled, but devices connected via the USB interface are not detected by the system, then check the registry editor, device manager and group policy editor. It is possible that changes were made to the system through them, due to which the ports are no longer working. You should start with the Registry Editor.

If USB support is enabled in the Registry Editor, check the controller drivers in Device Manager.

If you see an icon next to the controller that looks like exclamation point, and you are sure that the interface is supported in the registry editor, then this means that there are problems with the drivers. First try updating the software:

If update software controller did not help, update the driver motherboard. Download it from the manufacturer's website and install it manually. Another way to update the drivers of all controllers at once is to remove them from the system. Right-click on the controllers and select "Delete". After a reboot, the system will automatically install controller drivers, so you no longer have to worry about how to enable the USB ports - they will work just like that.

If only removable devices connected via USB do not work, check in the Group Policy Editor to see if a read ban is set.

Find the Removable Devices: Deny Read option and set it to Disable. Problem identifying flash drives and external drives must disappear.

Hardware damage to ports

If your laptop's USB ports are damaged or south bridge on the motherboard, then no methods will help enable the interface. Therefore, if the connectors stop working after mechanical impact, liquid getting inside the housing, short circuit or other negative factors, you should take the laptop to a service center for diagnostics.

This article is devoted to the question of how to enable USB support in the BIOS. As it turns out, not all users know that the functions Universal Serial Bus (in Russian interpretation - “Universal Serial Bus”) can be enabled and configured through BIOS Setup. We will not focus on the circumstances due to which you may need this operation - they may be different. For example, you discovered that the USB devices on your computer are running slower than they should, and you want to check whether your computer's BIOS supports this bus standard latest version.

First, enter BIOS Setup when booting your computer and laptop. A separate article was devoted to how to do this on our website. It is worth noting, however, that the BIOS section with USB functions is not always obvious to the user. In addition, different BIOS manufacturers in different versions may have bus management functions located in different sections. This could be the Advanced, Integrated Peripherals, Onboard Devices, etc. sections.

It may, of course, happen that the section with the settings USB functions in your laptop's BIOS or desktop computer just no. This situation can most often occur in laptops, in which the number of options available to the user is not very large at all. In the BIOS of my HP netbook, for example, I did not find such an option, no matter how hard I looked. Well, that means it’s not fate...

Setting USB options in BIOS

The number and range of USB features you can adjust in the BIOS can also vary greatly depending on the version. Often in Setup you can install support for a USB mouse and keyboard, and attached external drives. You can also disable/enable the ability to connect USB devices altogether or enable support for a specific version, for example, USB 2.0.

List of the most common USB options (in different versions BIOS may have different names):

• USB Function – enable/disable the Universal Serial Bus controller
• USB 2.0 Controller Mode – switching the USB 2.0 controller to 1.1 mode and back
• Assign IRQ For USB – assign IRQ to USB devices
• USB Speed ​​– setting the operating speed USB bus
• – USB keyboard and mouse support
• USB Storage Support – support for external drives on this bus
• Emulation Type – setting USB drive emulation modes

Once you have set the option you need, be sure to save it by selecting the BIOS Setup “Exit and Save Changes” option to restart your computer.

When setting USB parameters in the BIOS, however, you should remember that they incorrect installation may cause any devices permanently connected to the Universal Serial Bus, such as a keyboard or mouse, to become inoperable.

Conclusion

In this article, you learned how to enable USB support, as well as set USB options in the BIOS of your computer or laptop. As a rule, this operation is quite simple and will not take you much time.

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 motherboard BIOS have gone wrong. 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 device: 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”.

There was a case with one friend when the USB ports stopped working. Replacing the 3-volt battery on the motherboard solved this problem.

That's all, friends! Thank you for your attention!
