    Probing wants a brief delay after probe string on some machines.
    
    Probably reached the point of diminishing returns for trying to get
    probing to work better.  Best option, where practical, is to avoid
    probing completely; when necessary, best run it once then avoid
    repeating it.  cryptech_muxd will probe if requested, but probing is
    never going to be reliable.  Dedicated VID:PID would be much better.
