Usb 3.0 is disabled. How to enable USB support in BIOS on your PC? Disconnecting unnecessary devices

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

Disconnecting 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 to see if there is a lot of the device connected to the laptop. When using a USB hub, the laptop may not be able to provide power to all devices, causing the USB connectors to stop responding. Before doing USB setting in the BIOS, disconnect unnecessary hardware from the laptop and check if the ports work. If nothing has changed, then restart the laptop and enter the BIOS.

Enabling ports in BIOS

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

In the case of a laptop, this screen does not appear because the function is activated. fast loading... You can temporarily disable this technology in the power supply parameters:

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

After rebooting, select Diagnostics, then go to Extra options»And open the UEFI firmware options. Click "Restart", the next start will bring up the BIOS UEFI interface.

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

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

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

In Phoenix AwardBIOS, go to the “Advanced” tab and go to the “USB configuration” section. All parameters inside must be set to "Enabled" in order to YUSB ports worked.

In all BIOS versions to save the configuration, press the F10 key and confirm the selection by writing "Y".

Windows setup

If ports are enabled in the BIOS, but USB devices are not detected by the system, then check the Registry Editor, Device Manager, and Group Policy Editor. Perhaps, through them, changes were made to the system, due to which the ports are now not working. You should start with the Registry Editor.

If USB is enabled in Registry Editor, 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. Try updating your software first:

If the 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 for all controllers at once is to remove them from the system. Right click on the controllers and choose Delete. After rebooting, the system will automatically install the controller drivers, so you no longer have to think about how to enable USB ports - they will work anyway.

If only removable devices connected via USB do not work, then check in the Group Policy Editor if the read block is set.

Find the Removable Devices: Disable Read option and set it to Disable. The problem with identifying flash drives and external drives should disappear.

Hardware damage to ports

If the laptop has damaged USB ports or the southbridge on motherboard, then no means will help to enable the interface. Therefore, if the connectors stop working after mechanical impact, the ingress of liquid into the case, short circuit or other negative factors, then you should carry the laptop to the service for diagnostics.

In the case of the system unit, some USB ports can be replaced independently, but in a laptop this is not possible, because all the connectors are soldered to the motherboard.

This article focuses on how to enable USB support in the BIOS. As it turns out, not all users know that the Universal Serial Bus functions (in the Russian interpretation - "Universal Serial Bus") can be enabled and configured via BIOS Setup... On circumstances that may require you to this operation, we will not focus on - they can be different. For example, you find that USB devices on your computer are running slower than they should, and you want to check if your computer's BIOS supports the latest version of this bus standard.

To get started, enter BIOS Setup when you boot your computer and laptop. A separate article on our website has been devoted to how to do this. It should be noted, however, that the BIOS section with USB functions is not always striking for the user. Besides, different BIOS manufacturers in different versions of the bus control functions can be placed in different sections. These can be Advanced, Integrated Peripherals, Onboard Devices, etc.

It may, of course, happen that the section with the setting 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 options are generally not very large. In the BIOS of my HP netbook, for example, I did not find such an option, no matter how I looked. Well, that means it's not destiny ...

Setting USB options in BIOS

The number and set of USB functions that you can adjust in the BIOS can also vary greatly depending on the version. Often in Setup, you can install support for USB mouse and keyboard attachable external storage... You can also disable / enable the ability to connect USB devices altogether or enable support separate version such as USB 2.0.

A 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 - switch the USB 2.0 controller to 1.1 mode and vice versa
Assign IRQ For USB - assigns 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 - set emulation modes for USB drives

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

When setting USB parameters in the BIOS, however, remember that their incorrect installation may cause non-functional devices that are permanently connected to the Universal Serial Bus, such as a keyboard or mouse.

Conclusion

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

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

Disable USB ports in BIOS settings

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

BIOS Award... We go into the BIOS settings and select the item Integrated Peripherals. Go to this menu... Then we just find the items: USB EHCI Controller, USB Keyboard Support, USB Mouse Support and Legacy USB storage detect and disable them by selecting the parameter Disabled... Then we just save the settings and restart the computer;

Phoenix-Award and AMI BIOS... We go into the settings and select the item Advanced (sometimes in some versions there may be a Peripherals item) or Advanced BIOS Features. Next, 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 disable them. Next, we save the settings and restart the PC.

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

Disable USB using the registry

This is a more appropriate way. In the registry, you can disable access of USB ports to specific devices rather than the ports themselves. At a time when almost everything is connected via USB, including a mouse and keyboard, then 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.

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

HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ USBSTOR

Find the item Start. Open it and specify a value 4 ... Save your settings and restart your computer. This section closes access of external drives to the port.

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

Disable USB via Device Manager

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

Important! The option of removing drivers for USB controllers will not work, because the first time the device is connected to the port, Windows will start installing the drivers.

Disconnect USB using Windows files

Denying access using the Local Group Policy Editor

You can also prohibit 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 disconnecting ports.

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

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

Outcome

Whatever the reason for the need to disable USB ports, you now know how to do it.

Sometimes it becomes necessary to disable USB ports on a computer or laptop in order to restrict access for connecting flash drives, hard drives and other USB devices. Disabling USB ports will help prevent any storage devices from being connected that could be used for theft important information or cause a virus to infect your computer and spread malicious software local network.

Restricting access to USB ports

Consider 7 ways with which you can block USB ports:

Disable USB through BIOS settings
Changing registry settings for USB devices
Disable USB ports in device manager
Uninstalling USB Controller Drivers
Using Microsoft Fix It 50061
Usage additional programs
Physical USB disconnect ports

1. Disable USB ports through BIOS settings

Enter BIOS settings.
Disable all items related to the USB controller (for example, USB Controller or Legacy USB Support).
After you have made these changes, you need to save the settings and exit the BIOS. This is usually done using the key F10.
Restart your computer and make sure the USB ports are disabled.

2. Enabling and Disabling USB Drives Using Registry Editor

If disabling via BIOS does not suit you, you can close access directly in the Windows OS itself using the registry.

The instructions below allow you to close access for various USB drives (for example, flash drives), but other devices such as keyboards, mice, printers, scanners will still work.

Open the Start menu -> Run, enter the command " regedit”And click OK to open the Registry Editor.
Continue to the next section
HKEY_LOCAL_MACHINE \ SYSTEM \ CurrentControlSet \ Services \ USBSTOR
In the right part of the window, find the item " Start”And double click on it to edit. Enter value " 4 »To block access to USB drives. Accordingly, if you enter again the value " 3 ”, Access will be re-opened.

Click OK, close Registry Editor and restart your computer.

The above method only works when installed driver USB controller. If for security reasons the driver has not been installed, the "Start" parameter can be automatically reset to "3" when the user connects USB stick and Windows will install the driver.

3. Disable USB ports in device manager

Right-click on the " Computer"And select the" Properties "item in the context menu. A window will open on the left side of which you need to click on the link " Device Manager».
In the device manager tree, find the item " USB controllers”And open it.
Disable controllers by right-clicking and selecting Disable from the menu.

This method does not always work. In the example shown in the figure above, disabling the controllers (the first 2 points) did not lead to the desired result. Disabling item 3 (USB Mass Storage) worked, but it only gives you the option to disconnect a single instance of the USB stick.

4. Removing USB controller drivers

Alternatively, to disable ports, you can simply uninstall USB driver controller. But the disadvantage of this method is that when the user connects a USB drive, Windows will check for drivers and, if they are absent, will offer to install the driver. This in turn will open up access to the USB device.

5. Prevent users from connecting USB storage devices using an application from Microsoft

Another way to deny access to USB drives is to use Microsoft Fix It 50061(http://support.microsoft.com/kb/823732/ru - the link may open near the mituta). The essence of this method lies in the fact that 2 conditions for solving the problem are considered:

The USB drive has not yet been installed on the computer
The USB device is already connected to the computer

Within the framework of this article, we will not consider this method in detail, especially since you can study it in detail on the Microsoft website using the link provided above.

It should also be noted that this way not suitable for all versions of Windows.

6. Using programs to disable / enable access to USB storage devices

There are many programs for setting the prohibition of access to USB ports. Let's consider one of them - the program USB Drive Disabler.

The program has a simple set of settings that allow you to deny / allow access to certain drives. Also, USB Drive Disabler allows you to configure alerts and access levels.

7. Disconnecting USB from the motherboard

While physically disconnecting the USB ports on your motherboard is nearly impossible, you can disable the ports on the front or top of your computer case by unplugging the cable that goes to the motherboard. This method will not completely close access to USB ports, but will reduce the likelihood of using drives by inexperienced users and those who are simply too lazy to connect devices to the back of the system unit.

! Addition

Deny access to removable media through the Group Policy Editor

IN modern versions Windows has the ability to restrict access to removable storage devices (including USB drives) using the local editor group policy.

Run gpedit.msc through the Run window (Win + R).
Continue to the next branch " Computer Configuration -> Administrative Templates -> System -> Access to Removable Storage Devices»
On the right side of the screen, find the item "Removable drives: Deny reading".
Activate this option (position "Enable").
