[sane-devel] [CANON] : canoscan 300 does not work anymore...

[Pierre SOUCHAY]

Hi,
I use sane 1.0.7 for a while with a canscan 300.
Unfortunatly, my old PC running this version of sane with saned died a few 
days ago.
So I tried to make this scanner work with my new PC running Debian and sane 
1.0.9 without success.
I use an old aha152x (the same used on the old PC...) directly connected to 
the Canoscan 300.

~$ cat /proc/scsi/scsi 
Attached devices: 
Host: scsi1 Channel: 00 Id: 01 Lun: 00
  Vendor: CANON    Model: IX-03035B        Rev: 2.01
  Type:   Scanner                          ANSI SCSI revision: 02

~$ sane-find-scanner
found SCSI scanner "CANON IX-03035B 2.01" at /dev/sg0

When I lauch xscanimage or scanimage, both segfault.
I join the log as attachments given by the following command and 
SANE_DEBUG_CANON fixed to 128 :

~$ scanimage -d canon:/dev/sg0 2> scanimage.log
Segmentation fault

So, to confirm my problem, I've chrooted to the hard disk of my old computer, 
the one with sane 1.0.7.
No, i can scan with the old version of sane !!!
My conclusion : there are no problems with my kernel or device permissions, 
the problem is internal to sane.
The problem only occurs with versions of sane > 1.0.7, maybe only with the 
1.0.9.

If I may help...

Thanks.

Regards.
