[sane-devel] Canoscan N1220U + RH 8.0 problem

[vraptor at employees.org]

I am having trouble getting my Canoscan N1220U scanner working
with a stock RH 8.0 install.

Here's the installed versions (from rpms):

xsane-0.84-8
sane-backends-1.0.8-5
sane-frontends-1.0.8-4
xsane-gimp-0.84-8
sane-backends-devel-1.0.8-5

Scanner is showing up when plugged in:

Feb  5 02:43:30 linux-test /etc/hotplug/usb.agent: Setup scanner for USB product 4a9/2207/100

And, sane-find-scanner reports it:
sane-find-scanner: found USB scanner (vendor = 0x04a9, product = 0x2207) at device /dev/usb/scanner0

I have modified my /etc/sane.d/dll.conf to only include the plustek
reference. I have changed my /etc/sane.d/plustek.conf to include:

[usb] 0x4a9 0x2207
device /dev/usb/scanner0

And I added the following to my /etc/modules.conf (saw this suggested
in archives for similar problem for a different scanner):

options scanner vendor=0x4a9 product=0x2207

However, xsane refuses to recognize the scanner with "no devices
available" error dialog.  As found in other trouble-shooting
threads, I ran scanimage with debugging:

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

Obviously, the most significant point there seems to be "[plustek]
Device >0x04A9-0x2207<, is not supported!"  I double-checked, and
scanner.h in the local kernel source has this listed...

Perms on the device are:
crw-------    1 nmiller  root     180,  48 Aug 30 16:31 /dev/usb/scanner0

No link for /dev/scanner.

Thanks for any suggestions.  I'm open to removing rpm's and compiling
from source, but would appreciate comments on what's missing and how
installing from scratch would fix it.
