Lenovo W520 back usb port not working
- by jaudette
The usb port in the back of my laptop (on the right side when viewed from using perspective) is not working.
Does anybody know if we can get this port working, and what the port number is.
Here is my lsusb, if it can help.

I am running 12.10, upgraded from 12.04 but it did not work either in 12.04.
The two usb ports on the left work just fine.
EDIT:
I just updated my bios from 1.32 to 1.39, no change in behaviour.
The port does not even power up my devices.
EDIT 2:
Booted up windows, and the port is working.
I went into the device manager and looked at the USB settings.
I found my USB drive on Port 2, Hub 3, i just don't know how that relates to the Bus and Device numbers of linux.
In windows, Smart card reader was on USB hub located at port 1 hub 2, fingerprint and bluetooth were on USB hub located at port 1 hub 1
EDIT 3:
Went and looked at this SO post. Tried to look at my kern.log file with tail -f /var/log/kern.log. Got some activity when plugging/removing devices in other ports, but nothing happens when connecting a device into that port. It really looks disabled.
Looked at my usb1-4 sys/bus/usb/devices/usb1/power/control and they are all set on auto. As expected, usb4 have version 3.00, the others (usb1-usb3) are 2.00.
