Tried asking this on ubuntuforums but nothing forthcoming there. Here's my issue:

Hello I wonder if someone can help me with this. I have searched but yet to find an answer that works.

Ubuntu 14.04 fresh install on a custom built PC using a Gigabyte 990XA-UD3 motherboard. The BIOS was updated to the latest version using Q-flash and I chose to load the defaults (where it said everything would work).

USB 3.0 ports work, USB 2.0 ports do not and there are 8 xUSD 2.0 ports and 3x USB 3.0 ports. Physically for example I plug in the USB mouse I am using into a USB 2.0 port, the laser light flashes, then goes off. The mouse fails to work, as does any other USB device plugged into the USB 2.0 ports.

when I run dmesg I see (at the end)

When done, the only things plugged into the USB 3.0 ports are the keyboard and mouse. Help! at the moment the PC is looking like a very high powered doorstop.
