My MotherBoard is M7NCD Pro (BioStar), the manu says this board has 6 USB2.0 port, but when I connect my external 2.0 hard drive to it, it only runs in USB1.1 speed, while this external harddisk works fine in USB 2.0 speed in other machines. What is my problem?

By the way, I set the power source selection for USB to be "+5 Standby Voltage".

Thanks.

Do you have a listing for a "USB enhanced host controller" under device manager?
What version of Windows are you running?
