  4. Kernel Modules (Linux):
    • Be cautious when unbinding/bindings kernel modules, as it may affect other system functionalities.

1. Open Device Manager

USB ports allow you to quickly connect a variety of devices like keyboards, mice, and external hard drives. USB also allows you to charge your cell phone, MP3 player, or digital camera. However, this ease of use can be a security risk for businesses as it can lead to data theft and inject harmful viruses into the network. To prevent this, businesses block USB port access. This can be done using a dedicated software application, the Device Manager, or by editing the registry.

In order to disable USB ports on your computer, you will need to open the Device Manager. Once you have opened the device manager, expand the “Universal Serial Bus controllers” heading. From here you can disable any remaining USB options by clicking them, selecting Action, and then Disable device. You can then close the Device Manager and your USB ports will be disabled. There are many alternatives to this method, including purchasing a device that physically blocks the USB port (these devices typically require a special tool or key to remove and can be expensive). Another option is to utilize a software application such as Access Patrol, which provides more granular control over USB mass storage devices and other peripherals.

2. Right-click on the USB device

Having a disgruntled employee at work can be a serious threat to the company. They can introduce harmful viruses to the system, steal data and even destroy important files. Therefore, many companies have blocked USB ports in order to prevent them from being accessed by unauthorized users.

You can disable USB devices on your Windows computer by changing the registry settings. This trick works on all versions of Windows, including Windows 11/10. The process is simple and straightforward, requiring only a few clicks and a restart to get the job done.

In the Device Manager, expand Universal Serial Bus controllers, right-click USB Root Hub, and then select “Properties.” The same General, Driver, Details, and Power Management tabs appear as those for Generic USB Hub. If the value has a value of 4, change it to 3. Click OK, close the Registry Editor, and then restart your computer. The change will take effect as soon as you restart the computer. USB is a convenient and useful tool, but it can be vulnerable to malware that spreads through it.

3. Select “Properties”

The USB Selective Suspend feature, enabled by default in Windows, is supposed to save power by shutting down devices that have been idle for a while. But sometimes it can cause problems, especially with older devices that do not reconnect properly when the port turns back on.

To disable the USB Selective Suspend feature, you can use the registry editor. You will need to be logged in as an administrator. If you are unsure how to do this, consult your manual or online manual.

You can also change the power options for your computer’s USB ports. This can help reduce the risk of data loss from USB devices. However, it is important to remember that this can cause performance issues with your computer.

To disable the power options, you can use the registry editor or the BIOS setup utility. If you choose to use the BIOS or UEFI setup utility, be sure to save and exit the BIOS or UEFI settings before rebooting your computer. This will prevent any changes you made from being saved and applied to the next system boot.

4. Select “Power Management”

Sometimes, USB ports can stop working and require a reboot to regain functionality. This is due to a power management feature called “USB Selective Suspend” which can sometimes cause issues with USB devices. This problem is common on corporate computers and can be very frustrating for users. Fortunately, there is a way around this issue. You can enable your USB ports and drives by diving into the device manager and selecting the ’Universal Serial Bus controllers’ section. Once you find this, click the start option to open the ‘Edit DWORD value’ window. Enter ‘4’ in the value data and click OK.

After this, the USB Selective Suspend setting should be disabled. However, it is important to note that this method may not work on all PCs as it relies on the platform firmware to provide correct information about USB drivers. If this method does not work on your PC, you should try updating your USB drivers using a tool such as Advanced Driver Updater. This tool will scan your computer for outdated drivers and update them automatically.

5. Uncheck “Allow the computer to turn off this device to save power”.

USB ports are a blind spot for many organizations, and disgruntled employees can use them to steal data and spread harmful viruses. Disabling USB ports is a good way to prevent unauthorized data access and keep the network safe from infections.

To disable USB ports, you can either edit the registry or use a third-party software application. The registry editor is a powerful tool that contains important information, options, and settings for programs and hardware on the Windows operating system. However, it can cause serious problems if you make a mistake. Therefore, it is recommended to backup and restore the registry before making any changes.

To disable the USB ports, open the Device Manager and click on the Universal Serial Bus controllers heading. Then, right-click on the USB Root Hub and select “Disable device”. You may have one or more remaining USB options under the Universal Serial Bus controllers heading. Repeat this step for each of the remaining USB options. Note that this method will only disable USB mass storage devices, but keyboards and mice will still work.

Conclusion:

Enabling and disabling USB ports is a crucial aspect of system administration, especially for security-conscious users. Whether you are using Windows or Linux, there are multiple methods available to control USB port access. It’s essential to consider the security implications and choose the method that best suits your requirements. Always follow best practices, and if in doubt, consult the documentation for your specific operating system and seek professional advice.
