Note: no, the sd card in the kobo is not failing.

He has, which doesn't make much sense. I think the problem still lies within the cables and the Kobo being too picky about it. The USB hub in his computer shuts down after too many interruptions it thinks are caused by electro magnetic interference (the EMI lines from his log). Apparently it failed to power back up (possibly a failsafe mechanism to protect from harmful powersurges). If an EMI is false positive (and the cable or transmission itself is not to blame) then one or both sides (computer or Kobo) are not following standard protocol.
