I have had this motherboard since February this year, it has the F10 BIOS and I'm running Windows 7 x64.
I cannot get USB3 working from either of the headers on the board. It's fine from the connectors on the I/O panel but connecting the USB 2/3 front panel to either F_USB30_1 or F_USB30_1 just leads to the 'device not recognised' error. A USB2 device works fine in the same socket.
The device is a USB3 hard drive with its own power so shouldn't be a power issue.
Anybody have any ideas/suggestions? It's much more conveniant to use the sockets at the front rather than the back!
