Hello,
I second allan, it would be nice if you could test with at least last
stable
SANE release (1.0.20). But from the log sent, we can see that data reading is
failing during a calibration scan, while previous scans have succeeded. This
is rather uncommon. It happened that a few backends had some problems due to
'USB suspend and resume' at linux kernel level. See:
- http://lists.alioth.debian.org/pipermail/sane-devel/2007-July/019637.html
- https://bugs.launchpad.net/ubuntu/+source/sane-backends/+bug/85488
So I think it would be interesting if you could try some live cd to
test same
hardware with another kernel. Or test your scanner on another linux machine.
Since it _may_ be related to USB problems, you could look a kernel
messages
with the 'dmesg' command ? Another source of problem might be the usb port
used. On my laptop, only one of the 4 ports available works correctly with
scanners, so depending on which slot I plug scanners, they work or not.
Regards,
Stef
