Are you using Windows 7 or Windows 8? I'm going to guess that is an XHCI controller (USB 3.0)
Windows 7 does not come with native drivers for common USB 3.0 controllers, Windows 8 does.
You will need to take a look at your motherboard specifications to see which chip it is. Common USB 3.0 add-in controller manufacturers are NEC and ASMedia. Find out if it is one of those chips and if so, google for the drivers. Intel 7 series chipsets (excluding X79) have native USB 3.0 (not add-in) as well so you will have to get these drivers from Intel's website.
