Dear all,
I recently received a laptop (lenovo ThinkPad X220) at work with Ubuntu 12.04 64bit installed that works just fine except that one of the two usb ports doesn't work.
I have no idea how to find and solve the problem, so I would be grateful if you could help me.
When I connect my external usb hd to the port that doesn't work, the power led doesn't even turn on. The same is if I try to charge my Smartphone using usb,
neither it charges or detects that it has been connected to a USB port.
The other port works just fine.
Reading around I thought that you might be interested in the output of
Code:

Bus 002 Device 012: ID 04e8:689e Samsung Electronics Co., Ltd GT-S5670 [Galaxy Fit]
In this moment I am charging my mobile using the working USB port (that is the last device listed: Bus 002 Device 012: ID 04e8:689e Samsung Electronics Co., Ltd GT-S5670 [Galaxy Fit])
Also the output of:
Code:
dmesg | grep -i USB
just after connecting my external hd to the port that is not working is:
