I built a desktop pc and tried to install ubuntu 12.10 on a gigabyte 990-fxa ud3 board, but only my usb 3.0 ports worked. I googled a bit and made sure legacy support was on in the bios, but I can't come up with any other possible solutions. I also tried the most recent version of debian, and it had the same problems. This was on a live cd. Does anyone have an idea on how to correct this problem? I'd like to know if it can be solved before installing ubuntu. Thanks!
