One thing that would be handy would be details about each device when it 
gets stuck. Details such as:

* where was the device:
  1) Ubuntu (adb somehow not showing)
  2) Fastboot (maybe our flash procedure crapped out)
  3) Blank screen / don't know

* could unplug/replug the USB connector fix it?

etc. Then we'd have slightly more metrics.

Disabling MTP sounds interesting - However, AIUI, MTP is still going to 
cause havoc on the target that's really been our core problem. Still 
might be worth a shot given the pain we are currently experiencing.
