I just installed Ubuntu 13.04 (not, I'm new to Linux in general, but I've also tried to install 12.10 back before 13.04), and the USB ports aren't working. I had this problem in 12.10 as well. All of them (even the front two USB 3.0 ports on the front of my case) except the two USB 3.0 on my mobo (GA-990FXA-UD3) do not work.
Is there a way to fix this in Ubuntu, or is it a problem with my hardware?
CPU is an FX-8350 in case it's relevant.
