I've added to my config options USB_DEBUG
and turned on hw.usb.debug: 1 and hw.usb.umass.debug: 1 

This time the dump finished.

  DUMP: 95.35% done, finished in 0:03 at Thu Feb  9 23:06:21 2017
  DUMP: 99.23% done, finished in 0:00 at Thu Feb  9 23:08:19 2017
  DUMP: DUMP: 99117484 tape blocks
  DUMP: finished in 4916 seconds, throughput 20162 KBytes/sec
  DUMP: DUMP IS DONE

and log filled with-

I wonder if this is due to slightly reduced throughput? Will try again
without logging.
