I am having no luck getting some USB ports to work. I have plugged in my mouse into the back ports (directly on the motherboard, not the ones with the headers to the case's USB ports). It won't work.

I get this in dmesg:

Kernel is 3.2.0-30-generic. Same mouse (and two others) works when moved to front USB ports. Any ideas?
