[sane-devel] scanbd with canon

[Franz Fuder]

All,
just updated my system to suse 13.2 wiht 13.1 all was fine.

Compiled the scanbd 1.4.1 all fine with usb_enabled. In the foreground.
The scan is working fine. After the scanadf is finished I got a
segemtation fault from scanbd. It looks like that the usb system has a
problem and the device can not opened again. When I start scanbd after
the segemntatio fault it scans fine but the fault comes again.

I compiled and using the latest sane-backend from today. All programms
that I tested are working fine.

Any help for me in this group? Here is the output of scanbd

Cheers

Franz
