Unfortunately the trace isn't termendously helpful.  It shows a bunch
of reads with a few writes sprinkled among them.  Then for no apparent
reason, in the middle of a read the device was disconnected.

Oddly, the bulk-IN URB that was in progress when the disconnect
occurred did not complete immediately with an error.  Instead it timed
out after 30 seconds and was cancelled.  Sarah, I thought you had fixed
that?

The drive reconnected, was re-enumerated, and a few seconds later
disconnected again.  No way to know the reason for these disconnects;  
they could be symptoms of a bad connection, hardware/firmware bugs, or 
even possibly a bug in xhci-hcd.
