[sane-devel] trying Canon DR-3080C

[D. Hugh Redelmeier]

I have an old Canon DR 3080C sheet-feed scanner.  When I inherited it
SANE didn't support it (and neither does Vista) so I left it in a
corner.  I was about to dispose of it when I saw that Noah has written
the canon_dr driver.  Thanks!!

I have connected the scanner via SCSI to my up-to-date Ubuntu 9.10
AMD64 system with SANE 1.20.  (Vista doesn't support the SCSI card
either, but good old Linux does.)

The sane-canon_dr driver is listed as untested against this model.  So
I think that it should at least recognize the scanner.

sane-find-scanner sees it ('found SCSI scanner "CANON DR-3080C 2.07"
at /dev/sg2')

scanimage -L does not find it.

/etc/sane.d/canon_dr.conf seems to suggest it should.

I did an strace on scanimage -L.  It opened
/sys/bus/scsi/devices/6:0:0:0/{vendor,model,type} a whole bunch of
times.  Here's the one time that more was done with the device:

(There is no /dev/scsi directory.)

Any ideas?
