That's the SCSI simulation for IDE cd writers. At least in older Linux
versions it was known to make trouble with real SCSI devices. Try to
turn it off: rmmod idescsi (I think that's the name).

I'd expect "2 hosts left" because the first one is idescsi and the
second one the future domain host adapter?

Are you sure? It could be a link to "sg1" (without the "/"). That
means "the file sg1 in the same directory as the link itsself".

SANE should find the device even if /dev/scanner isn't there at all.

That's ok. As root, sane-find-scanner should find the scanner despite
the wrong permissions.

Show us the output of "cat /proc/scsi/scsi".
