That's a good point.  I wonder in this case if it is possible to keep a
list of what was there.  When you re-power if its not there, it should
be like it was disconnected, then act accordingly.  If it is there all
is ok.  It seems unlikely that the same PID/VID device would have
replaced it.  New devices would show up as not being there before.

Coding that all up would likely be a bunch of work assuming it was
possible.
