Status in “linux” package in Ubuntu: Triaged Bug description: My laptop has two usb ports, one 2.0 and the other 3.0. 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. WORKAROUND: Use USB 3.0 port.
