Disable usb 3.0 in hp bios. How to properly enable usb ports in BIOS. Prevent users from connecting USB storage devices using an app from Microsoft
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 to steal sensitive information or cause a virus to infect your computer and spread malicious software over your local network.
Restricting access to USB ports
Consider 7 wayswith which you can block USB ports:
- Disable USB through BIOS settings
- Change registry settings for USB devices
- Disable USB ports in device manager
- Uninstalling USB Controller Drivers
- Using Microsoft Fix It 50061
- Using additional programs
- Disable USB ports physically
1. Disable USB ports through BIOS settings
- Enter BIOS settings.
- Disable all USB controller related items (eg 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 with 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 Windows 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 -\u003e Run, enter the command " regedit”And click OK to open the Registry Editor.
- Proceed 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 works only when the USB controller driver is installed. If for security reasons the driver has not been installed, the "Start" setting may be automatically reset to "3" when the user plugs in the USB storage device and Windows installs the driver.
3. Disable USB ports in device manager
- Right-click on the " Computer"And select" Properties "from 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 drive.
4. Removing USB controller drivers
Alternatively, to disable the ports, you can simply uninstall the USB controller driver. But the disadvantage of this method is that when a 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 prevent access to USB drives is to use Microsoft Fix It 50061 (http://support.microsoft.com/kb/823732/ru - the link may open near mituta). The essence of this method is that 2 conditions for solving the problem are considered:
- The USB drive has not yet been installed on the computer
- 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 given above.
It should also be noted that this method is 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 almost impossible, you can disable the ports on the front or top of your computer case by disconnecting 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 of Windows, it is possible to restrict access to removable storage devices (including USB drives) using the Local Group Policy Editor.
- Run gpedit.mscthrough the Run window (Win + R).
- Continue to the next branch " Computer Configuration -\u003e Administrative Templates -\u003e System -\u003e Access to Removable Storage Devices»
- On the right side of the screen, find the item "Removable drives: Deny reading".
- Activate this option (position "Enable").
This section of local group policy allows you to configure read, write and execute access for different classes of removable media.
If your PC does not have USB ports 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 for 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 that is often found on modern laptops. It does not have a main page like AMI, but it is provided with 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 the 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:
Video: how to configure any BIOS to boot from a USB flash drive
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 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 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
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 the need to disable USB ports, you now know how to do it.
USB ports may stop functioning if drivers have failed, BIOS settings or connectors have received mechanical damage. The second case is often found among owners of a recently purchased or assembled computer, as well as those who decided to install an additional USB port in the motherboard or those who have previously reset the BIOS settings.
BIOS is subdivided into several versions and developers, therefore, in each of them the interface may differ significantly, but the functionality for the most part remains the same.
Option 1: Award BIOS
It is the most common developer of basic I / O systems with a standard interface. The instruction for it looks like this:
Option 2: Phoenix-Award & AMI BIOS
BIOS versions from developers such as Phoenix-Award and AMI have similar functionality, so they will be considered in the same version. The instructions for setting up USB ports in this case looks like this:
Option 3: UEFI interface
UEFI is a more modern analogue of BIOS with a graphical interface and the ability to control using a mouse, but in general, their functionality is very similar. The instruction for UEFI will look like this:
Connecting USB ports will not be difficult, regardless of the BIOS version. Once connected, you can connect a USB mouse and keyboard to your computer. If they were connected before, then their work will become more stable.
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 through BIOS Setup. On the circumstances, due to which you may need this operation, we will not focus on - they may 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.
First, 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. In addition, 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 there is simply no section for configuring 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 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 attached to external storage devices. You can also disable / enable the ability to connect USB devices altogether or enable support for a separate version, for example, USB 2.0.
A list of the most common USB options (different BIOS versions 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 back
- Assign IRQ For USB - assigns IRQ to USB devices
- USB Speed \u200b\u200b- set the speed of the 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
After setting the option you want, do not forget to save it by selecting the BIOS Setup option “Exit and Save Changes” to restart the computer.
When setting USB parameters in the BIOS, however, remember that incorrect setting may result in 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 you can enable USB support, as well as install USB options in the BIOS of a computer or laptop. As a rule, this operation is quite simple and does not take much of your time.
