You're right, of course. I should have thought of that - after all, I do have
two SCSI adapters in my PC - one BT-545S and a AHA-1510 (on an SB16/SCSI-2).

This makes life worse. You could represent the adapter numbers in the command
line some way, but this is effectively hard-coding the order in which they
get detected :-( Anybody see a way around this without building a list of devices
to be probed for multiple LUNs?
