USB port not functioning Fedora 17

edit

I am using fedora 17, Kernel Linux 3.6.11-1.fc17.x86_64, and 1 of my 2 usb ports is not working. One port is 3.0 and working fine. The other is 2.0 and is not working. On start up, if I place thumb drive in the port it will light up and stay lit until I choose to boot into fedora 17 and then it will stop. As a result, I do not think this is a hardware failure, but a possible driver conflict or wrong driver being used.

Also tried ubuntu, and after update, same problem.

After lspci -k two different controllers are shown to be present

00:14.0 USB Controller: Intel Corporation Panther Point USB xHCI Host Controller (rev 04)
Subsystem: Sony Corporation Device 90a8
Kernel driver in use: xhci_hcd

00:1a.0 USB Controller: Intel Corporation Panther Point USB Enhanced Host Controller #2 (rev 04)
Subsystem: Sony Corporation Device 90a8
Kernel driver in use: ehci_hcd

I can not seem to figure out what the problem is.
