Disabling usb 3.0 via bios. How to enable USB support in BIOS on your PC? Get help solving the problem

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 of Universal Serial Bus (in the Russian interpretation - “Universal Serial Bus”) can be enabled and configured through BIOS Setup. In circumstances where you may need to this operation, we will not focus attention - they may be different. For example, you find that the USB devices on your computer are running slower than they should, and you want to check whether your computer's BIOS supports the latest version of this bus standard.

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 manufacturers In different BIOS versions, bus management functions can be placed in different sections. This could be the Advanced, Integrated Peripherals, Onboard Devices, etc. sections.

It may, of course, happen that the section for setting up USB functions in the BIOS of your laptop or desktop computer simply no. This situation can most often occur in laptops in which the number available to the user There are not very many options 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 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 speed of the 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 their incorrect setting can lead to the inoperability of any devices permanently connected to the universal serial bus, such as a keyboard or mouse.

Please write in the comments below if you managed to solve the problem with a faulty USB 3.0 port, and what solution helped in your situation.

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 look to see if the device is connected to the laptop too much. 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 setting up USB in the BIOS, unplug any unnecessary hardware from your laptop and check if the ports work. If nothing has changed, then reboot the laptop and go into the BIOS.

Enabling ports in BIOS

To enter the BIOS during boot, press Delete, F2 or another key depending on the motherboard model. You can view it on the start screen.

In the case of a laptop, this screen does not appear because the function fast loading. 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:

Once rebooted, select Diagnostics, then go to Advanced Options and open UEFI Firmware Options. 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 four options to “Enabled”:

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” in order for USB ports worked.

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

Windows setup

If the ports are enabled in the BIOS, but connected via the interface USB devices 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 the registry editor supports USB interface is enabled, then check the controller drivers in Device Manager.

If you see an exclamation mark icon next to the controller, 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 motherboard driver. 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. The problem with identifying flash drives and external drives should disappear.

Hardware damage to ports

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

In the case of a system unit, some USB ports can be replaced independently, but in a laptop there is no such possibility, because all connectors are soldered to the motherboard.

First, you need to figure out why you might need to disconnect USB ports on your computer. Everything is quite simple here. With the advent of miniature data storage devices operating via USB, a need arose to prevent data leakage from computers. Using a regular flash drive or portable hard drive, you can easily steal any information. To prevent such incidents, it is necessary to completely disable USB ports. Of course, everyone may have their own reasons for disabling ports, but this is not so important. Below are several ways to disable USB ports on your computer.

Disable USB ports in BIOS settings

In fact, everything is quite simple: go to BIOS settings and disable all ports, or those that are necessary. The nuance is that on this moment There are several versions of BIOS, and port disabling is sometimes different in each.

BIOS Award. Go to the BIOS settings and select the item Integrated Peripherals. Let's go to this menu. Next, we simply find the points: USB EHCI Controller, USB Keyboard Support, USB Mouse Support and Legacy USB storage detect and disable them by selecting the option Disabled. Then we simply save the settings and restart the computer;

Phoenix Award And AMI BIOS. Go to settings and select the item Advanced (sometimes some versions may have a Peripherals item) or Advanced BIOS Features. Next we go to the menu USB Configuration. Next, turn off all USB items, save the settings and restart the computer;

UEFI. More modern panel. Go to the menu Peripherals or Advanced. Selecting items Legacy USB Support And USB 3.0 Support and turn them off. Next, save the settings and restart the PC.

Note! In some versions, the menu items may have slightly different names, but that's okay, just go through all the menus and find the USB settings.

Disable USB using the registry

This is a more suitable way. In the registry you can disable access of USB ports to specific devices, not the ports themselves. At a time when almost everything is connected via USB, including a mouse and keyboard, this method will be preferable. You can simply disable port access specifically to flash drives, but at the same time computer mouse will work fine.

Open the registry editor: keyboard shortcut Win+R, enter the command regedit and click OK. Next, move on to the next section:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\USBSTOR

Find an item Start. Open it and enter the value 4 . Save the settings and restart your computer. This section blocks access of external drives to the port.

Note! If you do not have them installed on your computer USB drivers controller, then the value Start will automatically change to the value 3 as soon as the device is connected to the port.

Disable USB via Device Manager

Open device Manager: right click on My computer, open Properties, Further device Manager. Open the menu USB controllers. Right-click and context menu select an item Disable.

Important! The option of removing drivers for USB controllers will not work, since the first time you connect the device to the port, Windows will begin installing the drivers.

Disable USB using Windows files

Denying access using the Local Group Policy Editor

You can also ban reading and writing.

Additionally

It is also worth mentioning that there are two more ways to restrict access to ports: restrict access using third party programs and physically disabling ports.

There is plenty of third-party software on the Internet, and each one is configured differently, so there is no point in describing this method in the article. All you need to do is find the desired program and instructions for it.

As for physically disabling ports, this method will only work with ports on the front panel of the system unit. Open system unit and carefully disconnect the wires going to the ports.
