I installed and used the scsiadd utility -- it does exactly what you
want. I used it all the time for EXACTLY the same reason up until a
few weeks ago.

There may be some way to make hotplug see it, but I never figured that out.

BTW to all the detractors -- a few months ago I walked into my office
and smelled smoke. It didn't take me long to discover it was my Agfa
SnapScan SCSI scanner. The MOV (Metal Oxide Varistor -- same component
in a cheapo surge supressor) -- burned up, as they apparently tend to
do. It probably would not have set fire to the office, but I caught it
quickly so I didn't find out. I was able to replace the MOV and it
still works, but I NEVER leave it on anymore. Before that happened, I
left my scanner on most of the time because the lamp turned off
automatically and I figured the power draw was minimal.
