Q: My motherboard is K7S8XE, what is the function of USB 2.0 controller option in the BIOS setup?(2004/2/17) A: If USB 2.0 controller is disabled, the USB controller will be 1.1 only. We realized that some USB devices, especially external USB box of hard disk drive, are over the USB 2.0 specification and it may not be recognized in the Windows OS. Under this situation, please disable the USB 2.0 controller.
