The components:
- Dell Precision M4800 laptop
- Dell docking station, with USB keyboard attached
Ubuntu 16.04 installed

=====================================================
If laptop lid is closed when resuming from suspend, screen will go black and
start spewing `unable to enumerate USB device on port` messages

==============================================================
1. Boot to laptop without docking station attached
2. Suspend
3. Attach to docking station with lid closed
