Your PC is made up of many devices that interact with each other. Although in most cases updating your drivers is the solution to USB problems, there may be PC settings (or other applications) interfering with your USB ports device.
The following steps outline what you need to do to uninstall USB Root Hubs, which may be preventing you from using your USB device. (Steps may vary slightly depending on the Windows OS you use.)
- From the Windows Start menu, click Control Panel.
- Click System.
- Select the Hardware tab.
- Click Device Manager.
- Scroll down to Universal Serial Bus controllers. You will see entries called Universal Root Hub.
- Right-click each one and select Uninstall.
- Restart your PC.
