Public bug reported:
My laptop has two usb ports, one 2.0 and the other 3.0. The 3.0 works
correctly (as far as i can see). The usb 2.0 port does nothing. It seems
to have power (a mp3 player took charge, but a cellphone did not) but
shows no activity otherwise. Whatever I plug in it nothing happens.
Nothing in dmesg, nor anything changes in lsusb. I've tried wireless
mouse, pendrive, hdd, couple cellphones. Everything works in the 3.0
port, does not in the 2.0 port.
The laptop is a Sony VAIO T13. It's a "ultrabook", with everything intel
inside.
