Hmm ... what SCSI ID have you assigned to the scanner? That
makes a difference.
Second -- is there a /dev/sk? (where ? corresponds to the SCSI
ID)? if not, cd to /dev and run the following script (assuming SCSI ID
5):
./MAKEDEV sk5
And a ls in /dev will subsequently show that there is a /dev/sk5, with
major and minor nodes somewhat like this:
======================================================================
popocat-2:csu 19:16 # l uk*
crw-r----- 1 root operator 120, 0 Nov 22 2003 uk0
popocat-2:csu 19:16 # ./MAKEDEV uk5
popocat-2:csu 19:17 # l uk*
crw-r----- 1 root operator 120, 0 Nov 22 2003 uk0
crw-r----- 1 root operator 120, 5 Oct 19 19:17 uk5
======================================================================
This was on a SS5 running OpenBSD 3.4, so the major device number may
differ on yours (120 on this system), but the minor device number should
match the SCSI ID of the device you need.

That *looks* as though it should do what you want, once you have
the right /dev/uk? created with /dev/MAKEDEV.
Good luck,
