U need to install the drivers for the USB3, they don't come included in the OS yet. If u try the USB2, it should work just fine.
The USB 2.0 devices dont work either on those 4 3.0 ports..... I installed the AMD All-in-one driver that came with the MB but i'll try downloading the new one from the site. I'm sure it has to be a driver issue or when I was having problems loading the OS i was messing with the bios a little. Maybe i should just reset the bios to default or see if there is an update for the bios as well.
