Answer by  tommdesktopconceptscom (19)

The USB port on your system may have a proprietary interface that is supported by your BIOS but requires driver software to be recognized by Windows. Check the processors manufacturer's site for driver code. Be sure to choose the Driver that is for your version of Windows. After that has been downloaded follow the installation instructions.

The reason could be that windows driver for the particular USB Port has not been installed properly. It could even be hardware problem with the USB controller.

Windows might not have the correct driver for your USB controller. Go to Device Manager, and look for any devices that have a yellow exclamation point, and right click them.
