[sane-devel] Problems with Canonscan 2700f

[Tobias Hovorka]

Hi everyone,

I've got problems to get my Canonscan 2700f work on Debian SID (Kernel
2.6.9).
I've tried backend versions 1.0.10, 1.0.14, 1.0.15 and patched the
module "sg" as described in [1].
Furthermore, I created the new group "scanner" with access to /dev/sg0
(660) and added my user to it.

Unfortunately, scanimage can't find my scanner.

Some informations which might be helpful:

$ sane-find-scanner
> found SCSI scanner "CANON IX-27015C 1.17" at /dev/scanner
> found SCSI scanner "CANON IX-27015C 1.17" at /dev/sg0

/usr/local/etc/sane.d/dll.conf
> #net
> canon
> pnm

/usr/local/etc/sane.d/canon.conf
> #canon.conf
> #scsi CANON
> #/dev/scanner
> /dev/sg0

cat /proc/scsi/scsi
> Attached devices:
> Host: scsi0 Channel: 00 Id: 04 Lun: 00
>   Vendor: CANON    Model: IX-27015C        Rev: 1.17
>   Type:   Scanner                          ANSI SCSI revision: 02

Finally, some debug output:

sanei_debug] Setting debug level of canon to 128.

Any help would be greatly appreciated.
