[ubuntu] USB ports have stopped working overnight Ubuntu 12.04

view story

http://ubuntuforums.org – I have spent all day on the Ubuntu forums and going through google search results, and everything I have tried so far (including downgrading the kernel) has gotten me nowhere, so I figured I would post my own thread and see if maybe someone could help find a specific solution to my problem. Basically my usb ports have simply stopped working. They will not read usb mouse or dvd drive. I also tried another mouse as well to make sure my mouse wasn't the problem. I know they are still recieving power because the laser lights up when I plug in my mouse. I simply can't get it to work. Besieds some (Hardware)
