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. Thanks, Richard W.
