Straight from Gigabyte:
* Due to a Windows 7 limitation, please connect your USB device(s) to the Intel controlled USB port(s) (located below the RJ-45 LAN port) before the VIA USB 3.0 controller driver is installed.
Thankyou very much was confusing the hell out of me
trying to install win7 on a new machine (never had USB3 before) and was getting desperate.
Joined just to say thanks
