How to disable usb ports. Tips for setting up the BIOS. USB ports on the front of the computer do not work

Today I will tell you how to enable booting from a flash drive in the BIOS of various manufacturers. No matter what version you have, the order of body movements will be as follows:

1. We insert our bootable USB flash drive into the USB connector of your computer. I recommend inserting it into a port located directly on the motherboard, i.e. from the back of the system unit.

2. Turn on the computer and press the key Delete(or F2) to get into the BIOS. Depending on the manufacturer and BIOS version, other keys (Esc, F1, Tab) may be used, so you need to carefully read the prompts on the screen.

In Bios, we can only navigate between tabs using the keyboard.
Below I will describe this process in detail using the most commonly used BIOS versions as an example.

Attention! Keep in mind that if you are installing the operating system from a flash drive or CD and have selected the boot device in the BIOS rather than in the boot menu, then after the first automatic reboot of Windows you will need to enter the BIOS again and return booting from the hard drive. If this is not done, autoboot from a flash drive or CD will work again, and Windows will begin the first stage of the procedure again installations.

Setting up Award Bios to boot from a flash drive

Award Bios:

First, let's check if the USB controller is enabled. Let's go to “Integrated Peripherals”. Use the arrow on the keyboard to move down to the “USB Controller” item. Press the “Enter” key and select “Enable” in the window that appears (also using “Enter”). Opposite “USB Controller 2.0” there should also be “Enable”.

Exit this tab by pressing “Esc”.

Then we go to “Advanced BIOS Features” – “Hard Disk Boot Priority”.Now in my example the hard drive comes first, but the flash drive should be there.

We stand on the line with the name of our flash drive (Patriot Memory) and raise it to the very top using the “+” key on the keyboard.

We leave here by pressing “Esc”.

Setting up AMI Bios to boot from a flash drive

If, after entering Bios, you see such a screen, it means you have AMI Bios:

First, let's check if the USB controller is enabled. Go to the “Advanced” – “USB Configuration” tab.

Opposite the items “USB Function” and “USB 2.0 Controller” should be “Enabled”.

If this is not the case, go to this line and press the “Enter” key. From the list that appears, select “Enabled” (also using “Enter”).
Then exit this tab by pressing “Esc”.

Let's go to the tab “Boot” – “Hard Disk Drives”.

Now my hard drive is in first place, but I need to put a flash drive here. We go to the first line, press “Enter” and in the window that appears, select our Patriot Memory flash drive.

It should be like this:

We leave here via “Esc”.

Select “Boot Device Priority”. Here, the first boot device must be a flash drive.

Press Esc.

Then we exit the Bios, saving all the settings made. To do this, go to “Exit” – “Exit & Save Changes” – “OK”.

Setting up Phoenix-Award Bios to boot from a flash drive

If, after entering Bios, you see such a screen, it means you have Phoenix-Award BIOS :

First, let's check if the USB controller is enabled. Go to the “Peripherals” tab – opposite the “USB Controller” and “USB 2.0 Controller” items there should be “Enabled”.

Then go to the “Advanced” tab and opposite “First Boot Device” set “USB-HDD”.

After that, exit the Bios, saving the changes. To do this, go to “Exit” – “Save & Exit Setup” – press the “Y” – “Enter” key

That's practically everything you need to know in order to boot from a flash drive. In my article, I described the process of setting up the BIOS of the most popular versions: Award And AMI. The third example presents Phoenix-Award Bios, which is much less common.
The described procedure may differ slightly in different BIOS versions. But the main thing is that you understand the principle of setting itself.

By the way, I would also like to add: in order to choose which device to boot your computer from, it is not necessary to change the settings in the BIOS. You can immediately call up a special menu after turning on the computer to select boot devices (this can be done by pressing the F8, F10, F11, F12 or Esc key). In order not to guess with the keys, look carefully at the monitor immediately after turning it on. We need to have time to see an inscription like this: “Press Esc to selest boot device.” In my case, it was necessary to press “Esc”.

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.

The user needs non-working USB ports to prevent strangers from stealing important information from the PC. 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 simplest solutions is to disable 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 Win + R key combination. In the 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 is 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 in the simplest way - through programs. One of these is USB Ports Disabler. This is a free program that 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.

Another utility worthy of attention. First of all, USB Manager is compatible with all versions of Windows. The program itself is lightweight, and installation will not raise any questions. The utility is completely multilingual, there will be no difficulties with the language. USB Manager disables/enables all USB ports on your PC in one click.

It is worth remembering that the main malicious files enter the system through USB drives, so by disabling the 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.

If the USB ports on your PC are not working, and Windows settings and driver updates do not help, the controller may have been 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 when the personal computer is turned on - before Windows starts loading from the hard drive.

Turn on your PC. In case it is already running: reboot. Wait for the speaker to beep: a short, single beep indicates that all internal components necessary for the computer to function 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 model of the installed motherboard and the BIOS firmware version. 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 do not have a graphical interface. This means that you will have to work only using the keyboard, like in the 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 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 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, such as 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 the motherboard has version 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, 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. It does not have a main page like AMI, but is equipped with convenient thematic bookmarks 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

Version of AMI 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 in the Windows registry. To do this you need to do the following:

Video: how to configure any BIOS to boot from a USB flash drive

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 Universal Serial Bus functions (in the 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 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 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 there is simply no section for setting up USB functions in the BIOS of your laptop or desktop computer. 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 (may have different names in different BIOS versions):

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.

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.

BIOS is a set of firmware located on a permanent memory chip located on the computer's motherboard. BIOS refers to that part of the system software that is designed to provide the operating system with access directly to the computer, as well as devices connected to it.

When you turn on your personal computer, the BIOS instantly recognizes the installed devices and, even before loading the operating system, checks their functionality and starts with the specified settings. During computer operation, this set of firmware is responsible for basic input/output functions, as well as for the quality of interaction of connected devices with each other.

Enable USB

USB support must be enabled in the BIOS, since many devices connect to the computer using this interface. To enable USB support in the BIOS, you first need to enter the BIOS setup utility by following these steps:

Start the computer in normal mode.
At the stage of checking devices (before loading the operating system), press the “Delete” or “Del” key (sometimes keys such as “F1”, “F2” or “F12” are used).

After entering the BIOS setup program, you can proceed directly to enabling USB support. This requires:

Find the menu item that contains the setting that enables USB support (depending on the BIOS manufacturer, it may be called “Advanced”, “Peripherals” or “Integrated Peripherals”).
Select the parameter responsible for the USB controller (for example, “USB Function”, “USB Controller”, “OnChip USB” or “USB Device”).
To enable USB support, set the parameter to “Enabled”.
Using items V1.1 and V1.1+V2.0, specify the operating mode of the USB controller (to enable USB 2.0 mode along with USB 1.1 mode, it is recommended to select item V1.1+V2.0).

Saving settings

In order not to enter the BIOS setup program each time when all the necessary steps have been completed, it is recommended to save the specified settings. This requires:
