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 discovered that USB devices your computer is running slower than it should, and you want to check whether your computer's BIOS supports the standard of this bus 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 BIOS section with USB functions is not always evident 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 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 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 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 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.
In many companies and organizations, a ban on the use of USB drives is one of the top priorities that they face. system administrator enterprises, the reason for this is two troubles - the removal of information (secret documents, etc.) and the entry of it: viruses, games, and the like. At first glance, the problem can be solved simply - disable through the BIOS USB ports, but this will also affect other USB devices - mouse, keyboard, printer or phone charger.
Banning USB through group policies in Windows server 2008
A ready-made group policy for banning drives appeared in server operating systems starting with Windows server 2008, you can configure them on the controller through the gpmc.msc snap-in, located in the same path (Policy > Computer configuration > Policies > Administrative Templates > System > Removable storage access). It works flawlessly, but can only be used in operating rooms Windows systems Vista, 7 and 8. 
The situation with Windows XP is somewhat more complicated; despite Microsoft's statements about ending support for XP in the spring of 2014, it still occupies a large part operating systems used in the corporate sector. It doesn’t matter, we’ll set it up like the local one, but only through the GPO. Launch gpmc.msc, create an object group policy and start editing it.
The USB interface is used everywhere to connect equipment, transfer data and charge devices. But sometimes users have a question about how to disable USB on a computer in order to protect data from copying or prevent the system from becoming infected with viruses.
BIOS Settings
You can disable ports directly in the BIOS. To do this, you need to restart the computer and, when turning it on, press the F2 key until the basic input/output system loads. Here you need to find items related to USB operation: for example, Legacy USB Support.
Deactivate the parameters by moving their value to the “Disabled” position. To save your changes, press F10 and then Y.
Windows Tools
Windows OS provides users with a variety of USB port management tools. Let's consider several options for disabling all ports or only individual connectors.
If you can't figure out which BIOS settings need to be disabled, then use Device Manager to disable USB. Here you can disable both all connectors and individual ports.
You can turn off all ports or only some connectors to which flash drives or other external drives are connected. Alternatively, you can completely remove hardware drivers, but this method does not always work. When you connect a USB device, the system will detect that you need software no, and will begin installing it on its own.
If you are not afraid to work with the Registry Editor, then use it to deactivate all USB ports.
If you need to turn USB back on, go to the specified registry branch again through the editor and change the value of the “Start” parameter from “4” to “3”.
In some Windows versions(Ultimate, Professional) can be used to disable Group Policy Editor.
As you can see, this parameter is responsible specifically for prohibiting data recording. Simply put, the ports will work, but you won’t be able to write anything to external drives.
If Windows tools seem inconvenient to use, then use it to disable USB program Ports Disabler, which with one click disables the USBSTOR service, which is responsible for the operation of all USB ports on the computer. The program disables only ports intended for external drives (flash drives, hard drives), whereas the same adapter wireless mouse continues to work quietly.
After disabling the ports, no external drive will be detected on the computer. If you need to turn the connectors back on, click the “Enable USB” button in the program.
Physical shutdown
To prevent the ports from working, you need to turn off their power. Those connectors that are on the rear panel system unit, it will be difficult to disconnect from the motherboard.
If you need to turn off USB on the front panel of the system unit, it is easier to disconnect the wires.
This method does not completely block access to the USB interface, since the ports at the back will continue to work, but it will at least discourage users from inserting flash drives into the slots at the front, as a result of which the media often ends up broken due to careless handling.

If the USB ports on your PC are not working and Windows settings and driver updates do not help, perhaps the controller was disabled in the BIOS. In this case, you will need to go to the configuration menu and turn everything back on.
There are many different versions BIOS with its own interfaces and subtleties of operation. Also, a more modern complex can work on your computer - UEFI, which supports a full GUI interface. This article discusses the distributions that are most often installed on motherboards.
Entering BIOS settings
To start changing the configuration, you need to go to the corresponding menu. It can be opened during power on personal computer- before it started Windows boot from the hard drive.
Turn on your PC. In case it is already running: reboot. Wait sound signal Speaker: A short single beep indicates that all internal components necessary for the computer to operate have been detected.
Now you need to click hotkey to call the configuration. This must be done before changing the screen. If you don't have time and Windows starts loading, reboot. The keys depend on the installed motherboard model and version BIOS firmware. You can find it in the user manual that came with the motherboard, on the manufacturer’s official website, or view on your PC screen when loading it:
If you don't know the board model, it's okay. Just try pressing the following keys: Tab, Delete, Esc, F1, F2, F8, F10, F11, F12. One of them will definitely do.
You don't have to try just 1 option at a time. You can quickly press all the buttons from the list without any problems. One of them will come up and launch the BIOS settings, and the rest will be ignored.
Entering the BIOS/UEFI settings of the latest PCs
Many modern computers boot up so quickly that you won't be able to access the keystrokes when you turn them on. This is also true for laptops. Therefore, the latest versions of Windows OS have acquired a new launch feature. Let's show it using Windows 8.1 as an example.
Your computer or laptop will reboot into setup mode. After restarting your PC, you will also be able to select option to run from a USB drive or DVD.
Menu navigation
Almost all BIOS versions are devoid of GUI. This means that you will have to work only using the keyboard, as in, for example, Windows console. Navigation is carried out using the up-down and right-left arrows. To open any section, use the Enter key to go back - “Escape”. A small reminder of the keys used is always shown on the screen.
Firmware complex UEFI installed on the most expensive and powerful motherboards. It supports more drivers and can use a mouse. Its interface will be familiar Windows users and other modern operating systems.
Each version has its own interface and sets of options. Even the names of the same parameters may differ. The following article describes several popular BIOS releases.
AMI BIOS
A very common option that can be found on many modern computers. The main menu is divided into 2 parts: a list of categories and various actions, like exit or save. You will be working on the left side.
You need to go to the section called “ Integrated Peripherals" There is no Russian version of the interface, so all commands are only in English. Use the Down arrow to highlight this item and press Enter.
Here you need to enable ( Enabled) 4 options:
- USB EHCI controller– main controller. If on motherboard there are ports of version 3.0, this item will be divided into 2 parts: “Controller” and “Controller 2.0”;
- USB Keyboard Support– keyboard support;
- USB Mouse Support– mouse support;
- – work with external data storage: flash drives, disk drives, smartphones and digital cameras.
In some older versions there are only 2 points " USB controller" And " Legacy USB storage support».
When you're done with the settings, press the F10 key to save your changes and restart your computer.
Phoenix AwardBIOS
Another popular version that can often be found on modern laptops. Doesn't have home page, like AMI, but with convenient thematic tabs at the top. You can move between sections using the left and right arrows, and between items using the up and down arrows.
Go to the section " Advanced» using the Right arrow. In it, find the category “ USB configuration" All items in this section must be moved to the position “ Enabled" In some versions the category " USB configuration" may be located in the " tab Peripherals" and not in "Advanced".
To exit the menu, press F10 and confirm exit.
AMI BIOS for Asus
AMI version used on Asus laptops. Externally it is very similar to Phoenix - a similar bookmarks bar. Settings USB are in the section " Advanced" Go there, enable all options and exit using the F10 button.
UEFI
Contrary to popular belief, UEFI is not part of the BIOS. It can rather be called a more advanced, but less popular competitor. There are a large number of different versions, each with their own interfaces. However, here the controls are similar to the usual Windows, so you can easily find the options you need.
Windows Settings
If at the BIOS level all ports and controllers are enabled, but the USB ports still do not work, there may be a problem in the settings of your Windows system.
First, just try disconnect and reconnect the device. This will check if the drivers are correct. If there's something wrong with them, Windows will try to reinstall them.
If nothing happens when you reconnect, try turn on the controller V Windows registry. To do this you need to do the following:

Modern PCs are very productive, they are capable of processing hundreds of tasks per second. If you connect a third-party device to it, the performance will increase significantly. This could be a scanner or printer, smartphone or webcam. All this makes the computer a unique tool.
Non-working USB ports are needed by the user so that strangers cannot steal from the PC important information. This is a kind of privacy policy. A person will not be able to connect a flash drive or hard drive with a USB connector in order to copy important data. But it is important to ensure that the keyboard and mouse connectors remain functional. One of the most simple solutions is disabling USB ports through the registry on Windows 10. The main advantage of this method is that you do not need to download different software, thereby cluttering your PC
So let's get started. Press the key combination Win + R. command line write regedit and press Enter.
A register appeared in front of us. In its left part we find the *HKEY_LOCAL_MACHINE* section and double-click on it. There is a *SYSTEM* folder in which the *CurrentControlSe* subsection is hidden. Next, we find * Services * and in it we look for *USBSTOR*. On the right side of the registry, find the *Start* value and click on it. The *Change DWORD Parameter* window will open in front of you. To disable ports, select 4 instead of 3 in the *Values* field.
3 – enable USB ports, 4 – disable. Now we reboot the PC and find that the USB ports are disabled.
Everything is very simple here. Right-click on *My Computer* and select Properties.
In the window that opens, select the *Device Manager* section.
Before us is a tree of all the devices on our PC. Find and select *USB Controllers*. We selected this section and, using RMB, disable all the necessary ports.
It is worth noting that this method not always efficient. There have been cases when 2 out of 4 ports or one were disabled.
Using third party programs
You can set a ban on USB ports by in a simple way– through programs. One of these is USB Ports Disabler. This free program, which disables all ports on your PC. The utility has a very simple and minimalistic interface. The program is free. USB Ports Disabler detects and disables USBSTOR, which we saw in the registry. Thus, reading data from a USB drive will be impossible.

It is worth remembering that the main malicious files enter the system through USB drives, so by disabling read ports, you will thereby protect yourself from headaches. You can select a specific connector that you would like to disable, this could be a connector for a printer or scanner. The program itself works quickly, clearly and correctly. The software is updated very often; by the way, the latest version has an updated shutdown system for the user.
