  2. Navigate to the “Advanced” or “Integrated Peripherals” section.
  3. Look for an option related to USB configuration.
  4. Ensure that USB support is enabled. If there’s an option for USB 3.0/3.1, make sure it’s enabled if you’re using those ports.
  5. Save changes and exit. The system will reboot with the new settings.

Power Management Settings (Windows):

  1. Open Device Manager (Win + X and select “Device Manager”).
  2. Expand the “Universal Serial Bus controllers” section.
  3. Right-click on each USB Root Hub and select “Properties.”
  4. Go to the “Power Management” tab.
  5. Uncheck the option that says “Allow the computer to turn off this device to save power.”
  6. Repeat this process for all USB Root Hubs.

Group Policy Settings (Windows):

  1. Press Win + R to open the Run dialog box.
  2. Type gpedit.msc and press Enter to open the Group Policy Editor.
  3. Navigate to “Computer Configuration” -> “Administrative Templates” -> “System” -> “Removable Storage Access.”
  4. Double-click on “All Removable Storage classes: Deny all access.”
  5. Set it to “Disabled” and click “OK.”
  6. Restart your computer for the changes to take effect.

Check for Driver Updates:

Outdated or incompatible drivers can cause USB port issues. Visit the official website of your computer or motherboard manufacturer to download and install the latest USB drivers.

Scan for Malware:

Malware or viruses can interfere with USB functionality. Run a thorough antivirus scan to ensure your system is clean.

1. Device Manager

USB ports allow you to quickly connect and use a variety of devices, such as a keyboard, mouse or external hard drive. They also enable you to transfer data between these devices and your computer. If you’re experiencing USB problems, the problem may be due to a hardware or software issue. You can easily resolve these issues by using the Device Manager or the Registry Editor.

To check the status of your USB ports, open Device Manager and expand the Universal Serial Bus controllers branch. If a USB device isn’t working properly, it will appear with a yellow exclamation point.

You can also view detailed information about a specific USB device by right-clicking on it and selecting Properties. In the Device Properties window, you can view the Driver tab, which displays the driver version and other information about the device. The Details tab shows the resource memory settings and IRQ of the device. If you’re using an Enhanced Host Controller Interface (EHCI) USB driver, you can also view the USB 2.0 common code and the existing class drivers.

If your USB devices aren’t working properly, the issue may be caused by a bad device driver. To fix this, uninstall the old device driver and install the latest one. If the problem persists, you can try updating the motherboard drivers.

2. Registry Editor

Using USB ports on your Windows PC allows you to transfer files from one device to another. However, if your IT administrator has blocked the USB ports on your computer, you may not be able to access those devices or copy the files to them. Luckily, there are several ways you can reset or enable USB Ports on your computer that have been disabled by your IT administrator.

First, you need to make sure your Windows files are backed up. This will protect your Windows data in case anything goes wrong with the registry editing process. Then, you can open the local group policy editor by going to “Computer configuration” – “Administrative templates” – “System” – “Removable Storage Access”.

In the right pane, you will see an entry called USB selective suspend settings. Double-click the entry and change its value to 3. This will allow you to use USB devices on your Windows computer.

This will help you prevent unauthorized file copying and viruses from spreading between computers. This method is quick, easy, and free, so you should try it out. It works on all versions of Windows, including Windows 11 and Windows 10. This trick will help you keep your Windows computer invulnerable to unauthorized copying or virus spread through USB devices.


The BIOS is a multi-purpose stored, read-only memory device on the system board that can enable or disable integrated and peripheral components installed on the computer. The BIOS also has an option to disable external USB ports but maintain full support for internal USB devices managed by the ROM and OS.

Disabling the USB ports prevents users from connecting and using USB storage drives to steal confidential information, carry harmful viruses and other malware into the network. This is especially important in work environments where disgruntled employees can use unauthorized devices to bring in malicious content that could collapse the entire network.

You can disable the USB boot on all nodes in a PowerScale cluster by entering the BIOS, changing the USB boot setting to “Disabled” and saving and exiting the BIOS. This may increase the amount of time needed to perform a service operation on the node because it requires a service person to have the BIOS password (if configured), enter the BIOS and modify the settings, then re-disable the USB port access after the service is completed.

It is not possible to disconnect USB ports from the motherboard but you can remove the USB connections from any USB hubs on the front and top of the computer by unplugging the cable from the header. Some computer manufacturers provide a tool for managing USB functionality through the BIOS that includes enabling or disabling the USB ports and legacy USB support.

4. Software

There is no way to disable USB ports using software, unless you are able to determine which hub each port connects to. The only way to do this is to use the Windows Device Manager (set to devices by connection mode) to see which hub each port connects to and then disable that hub. This will disable all the ports that are connected to that hub.

USB devices like flash drives can be dangerous for a business if they contain viruses or stolen data. Disgruntled employees are often able to access the company network through USB ports and steal confidential information or spread harmful viruses throughout the system. Fortunately, there are several ways to prevent data breaches and lost files by blocking USB ports or USB devices on your computer.

The best way to block USB ports and prevent the loss of data is by using a dedicated software solution such as Current Ware’s Access Patrol USB device control. This granular USB device blocking software allows you to configure device permissions based on users, computers, or workgroups. For example, you can disable USB mass storage devices but allow keyboards and mice. You can also set the software to only apply these restrictions to USB devices in the Allowed List, allowing users to still use their authorized USB devices even if the policy is disabled for all other devices.


Enabling USB ports involves checking both hardware and software components. By verifying physical connections, inspecting device manager details, adjusting system settings in BIOS/UEFI, managing power options, and updating drivers, you can troubleshoot and enable USB ports effectively. If issues persist, it might be necessary to seek professional assistance or consult the documentation specific to your computer or motherboard model.
