That's a problem with the SCSI bus: At least its simple variants, as
used by scanners, are not hotplugging-aware, so there is no way to
detect if a device is powered on or off. (BTW, better avoid to
(dis-)connect SCSI devices while any device on the bus is powered
on: this can destroy the driver transistors, no joke. And _never_ do
this with NCR5380 SCSI bus chips. For these chips, fortunately quite
old ones and today not often found in use, it is a safe bet that
they are broken after hotplugging ;)
