i will try this, but it will be fairly complicated.
i boot from ide drives (blush) so it is possible.

it doesnt really give any errors except those i posted.
the symptoms is that the scanner command(whichever i try)
just stops. the scanner hums slightly and the communication led
on the front flashes, but thats about it.

also, i now have terminated the scanner scsi bus, and the
symptoms are the same.

the symptoms are not always the same. sometimes the scanner dissapears
when i do find-scanners. sometimes it seems like the unit on the
other card with the same id as the scanner on that bus, apears in its
place on /dev/sge, but im not certain.

i dont understand why find-scanner finds the snapscan at both
/dev/sge and /dev/sg4. before doing my big-bang upgrade to new box
and new kernel, it only appeared on /dev/sgf.

it is all very strange and i dont know how to debug my setup in
a rational fashion. going down to a simpler setup is a start i guess,
so i will try that. thanks!
