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 an ordinary USB flash drive or portable hard drive, 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 the BIOS settings and disable all ports, or those that are necessary. The nuance is that at the moment there are several versions of the BIOS, and the disabling of ports in each is sometimes different.

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 some versions may have 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 Supportand 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, and not 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 the 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 blocks 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

Discover 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, since the first time you connect the device 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 disable ports.

There are plenty of third-party software on the Internet, and each is configured in its own way, so it makes no sense to describe this method in the article. All you need is to find the required 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 the system unit and carefully disconnect the wires going to the ports.

Outcome

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

On some computers, when you connect a hard drive or USB 3.0 stick, the error “The device is not recognized " (USB Device Not Recognized) or " Windows has stopped this device because it reported a problem.(Code 43)"in the device manager.

In this article, you will find instructions on how to fix the following problems:

• USB device not recognized / not detected
• USB 3.0 flash drive not recognized / not detected

If the USB ports do not work on your PC, and Windows settings and driver updates do not help, the controller may have been disabled in the BIOS. In this case, you need to go to the configuration menu and turn everything back on.

There are many different versions BIOS with their interfaces and subtleties of work. Also, a more modern complex can run on your computer - UEFIwhich supports a full graphical 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 when the personal computer is turned on - before Windows starts booting from the hard disk.

Turn on your PC. In case it is already working: reboot. Wait for the speaker beep: a short single beep indicates that all the internal components required 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 do not have time, and Windows starts loading, reboot. Keys vary depending on motherboard model installed and BIOS firmware version. You can find it out in the user manual that comes with the motherboard, on the manufacturer's official website, or look at your PC screen when loading it:

If you don't know the board model, that's okay. Just try pressing the following keys: Tab, Delete, Esc, F1, F2, F8, F10, F11, F12. One of them will probably do.

You don't have to try only 1 option at a time. You can quickly press all 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 BIOS / UEFI Settings on Latest PCs

Many modern computers boot up so quickly that you won't be able to hit by pressing the keys at startup. This is also true for laptops. Therefore, the latest versions of Windows have a new startup feature. Let's show it using the example of Windows 8.1.

Your computer or laptop will reboot into setup mode. After restarting your PC, you can also choose option to start from a USB stickor DVD disc.

Menu navigation

Almost all BIOS versions lack a graphical interface. This means that you only have to work with the keyboard, such as in the Windows console. Navigation is carried out using the arrows "up-down" and "right" - "left". 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.

Complex of microprograms UEFI installed on the most expensive and powerful motherboards. It supports more drivers and knows how to work with a mouse... Its interface will be familiar to users of Windows 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 article further describes several popular BIOS releases.

AMI BIOS

A very common variant that can be found on many modern computers. The main menu is divided into 2 parts: a list of categories and various actions, like exiting or saving. You will be working on the left side.

You need to go to the section called " Integrated peripherals". There is no Russian-language version of the interface, so all commands are in English only. Use the Down Arrow to highlight the item and press Enter.

Here you need to include ( Enabled) 4 options:

• USB EHCI controller - the main controller. If the motherboard has 3.0 ports, 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, disks of smartphones and digital cameras.

Some older versions have only 2 items " 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 often found on modern laptops. It doesn't have a main page like AMI, but it has convenient thematic tabs at the top. You can navigate between sections using the "left" - "right" arrows, and between items - using the "up" and "down".

Go to the section " Advanced"Using the Right arrow. Find the category “ USB configuration". All items in this section must be translated into the position " Enabled". In some versions, the category " USB configuration"Can be in the" Peripherals"And not in" Advanced ".

To exit the menu press F10 and confirm exit.

AMI BIOS for Asus

The AMI version used on Asus laptops. Externally very similar to Phoenix - a similar bookmarks bar. Settings USBare in the section " Advanced". Go there, enable all options and exit with the F10 button.

UEFI

Contrary to popular belief, UEFI is not part of the BIOS. Rather, it can be called a more advanced, but less popular competitor. There are many different versions, each with their own interfaces. However, the control here is similar to the familiar 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, the problem may be in the settings of your Windows system.

First, try simply disconnect and reconnect the device... This will cause the drivers to be checked for correctness. If something is wrong with them, Windows will try to reinstall them.

If nothing happens when reconnecting, try turn on the controller in the Windows registry. To do this, you need to do the following:
