I'm running Xubuntu 12.04 on an Asus X83V Laptop and a couple days ago, all my USB ports stopped responding, with neither my mouse nor flash drives or any usb devices responding. When I connect my phone to any USB port it does charge, but does not connect to my laptop. The same goes with my mouse, which lights up but doesn't respond.

My lsusb output with or without any devices connected is:

~$ lsusb  
Bus 001 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub  
Bus 002 Device 001: ID 1d6b:0002 Linux Foundation 2.0 root hub  
Bus 003 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub

Bus 008 Device 001: ID 1d6b:0001 Linux Foundation 1.1 root hub 

Running dmesg gives me the following recurring output:

I'm running kernel 3.2.0-34-generic and have tried updating it to 3.6 but to no avail. SOS?

I an getting similar output to you on demsg, but I know my onboard controller is bad. Are you certain yours is working normally? –  meteorainer Apr 18 '13 at 21:05
