[sane-devel] Scanner works fine, but with a lot of error (?) messages in /var/log/messages

[Martin Kho]

Hi,

My Epson Perfection 1650 (internal name: GT 8200) works as expected. The 
problem is that I get the following messages when using 
sane-find-scanner, scanimage or any other frontend:

cat /var/log/messages:
kernel: scanner.c: open_scanner(1): Unable to access minor data
kernel: scanner.c: open_scanner(2): Unable to access minor data
kernel: scanner.c: open_scanner(3): Unable to access minor data

kernel: scanner.c: open_scanner(5): Unable to access minor data
kernel: scanner.c: open_scanner(6): Unable to access minor data

kernel: scanner.c: open_scanner(13): Unable to access minor data
kernel: scanner.c: open_scanner(14): Unable to access minor data
kernel: scanner.c: open_scanner(15): Unable to access minor data
...

The scanner is found as minor 0: open_scanner(0) is ok. With version 1.0.5
i did't have these messages.

Other information:

- Red Hat 7.2 (all updates installed)
- Kernel 2.4.19 (build using RH config)
- Sane-backends-1.0.8 (build from src.rpm)
   (before installing this version, v1.0.5 was removed)
- Also tried Sane-backends-1.0.7 from RH7.3, but with the same odd results.

Can someone tell me what is wrong or what i'm doing wrong?

Thanks,
