SCSI module not installed for scanner?

[Charles Sullivan]

I have an HP-6200C scanner connected to my
Red Hat 9 (i386) system via an Advansys
ABP-960U SCSI card. Although 'dmesg' reports
that the card and scanner are recognized at
boot time, the Advansys module (advansys.o)
is apparently not installed. At least the
utility 'sane-find-scanner' can't find it.
(When I first installed the card, 'kudzu'
popped up and said it was configuring it.)

If I manually run 'insmod advansys', then
'sane-find-scanner' reports TWO scanner
devices, /dev/sg3 and /dev/sgd. (Could they
be synonyms?)

The situation may be complicated by the fact
that this HP model doesn't report itself as
a "Scanner" but as a "Processor" (sane
understands this however).

What do I need to do to make the system install
the module at boot time (and hopefully assign
the device /dev/scanner to it)?

Here's the section of 'dmesg' (I'm also using the
ide-scsi module for two IDE CD-ROMs);
-----------------------------
scsi1 : AdvanSys SCSI 3.3G: PCI Ultra: IO 0x1000-0x100F, IRQ 0x9
Vendor: HP Model: C6270A Rev: 3828
Type: Processor ANSI SCSI revision: 02
scsi : 1 host left.
Attached scsi CD-ROM sr0 at scsi0, channel 0, id 1, lun 0
Attached scsi CD-ROM sr1 at scsi0, channel 0, id 2, lun 0
sr0: scsi3-mmc drive: 0x/48x cd/rw xa/form2 cdda tray
Uniform CD-ROM driver Revision: 3.12
sr1: scsi3-mmc drive: 32x/32x writer cd/rw xa/form2 cdda tray
------------------------------

And here's what 'sane-find-scanner' reports after
manually installing the module:
----------------------
found SCSI processor "HP C6270A 3828" at /dev/sg3
found SCSI processor "HP C6270A 3828" at /dev/sgd
# Your SCSI scanner was detected. It may or may not be supported by SANE. Try
# scanimage -L and read the backend's manpage.
----------------------

(The scanner is in fact supported by sane, and 'xsane'
does work.)

Your advice and assistance will be much appreciated.

If this is the first time you've tried to use the scanner
with Linux, you might need to tweak /etc/sane.d/hp.conf to
get it to work. I don't have RH9, but I have used an HP
6300C with RH 6.1-8.0 using SCSI at first and now using
USB. IIRC, there is a how-to on using HP scanners. A
Google or Redhat search should find it.

If the issue is just installing the module at boot time,
then you can do that via /etc/rc.d/rc.local using a modprobe
or insmod command.

If RH9 still uses the old-style highly-populated /dev
directory, you can simply make a symlink from /dev/scanner
to /dev/sg3 or whatever it is. That's basically what I did
when I used SCSI with my scanner. You might need to check
the symlink every once in a while in case some up2date
package overwrites it.

Good luck.

Why didn't I think of that? :(
Yes, sgd is a symlink to sg3.

Yes, it does. But now I understand what is happening.

Thanks for your help.

I got stuck with this, too. I think that sane-find-scanner actually
probes all devices where a scanner can be connected.
