Public bug reported:
I have ubuntu 16.04.1 LTS installed on thinkpad x220. I Just purchased
an ultrabase 3 docking station, and after I dock the thinkpad, the usb
ports on the dock don't work and the little red light on the dock does
not light up, however the thinkpad does see that there is AC power and
the dvd drive in ultrabay works. I'm not using external monitor so I
haven't checked if vga or display port is working. The main thing is
that I want the usb ports to work for my keyboard and mouse.
I have found that if I sleep the thinkpad and then resume after docked
the red light will illuminate and usually the usb ports will then work.
So that is a workaround, but annoying.
Also it works properly if I reboot with the laptop docked.
But once I undock and then re-dock, the usb ports are dead, no light on
usb keyboard, nothing.
I also booted from an ubuntu 18.04 live usb and tried docking with same
result.
