I've just obtained a Canon N670U scanner, and have been trying to use it with xsane. However, I'm having problems with the scanner locking up part way through a scan or preview scan.
I'm using a freshly compiled sane 1.0.9, with plustek 0.45-TEST5 and xsane 0.90 on a Red Hat 8 system.
The lockups mainly occur when calibration is switched on in plustek.conf, but can occur with no calibration. Lockups also occur if I set the gain values manually in the config file.
Below is debug output from using xsane, where I've set the gain values manually, and calibration is switched off. The output is similar with calibration enabled.

After this, the scanner head moves some distance down the bed, and then stops, and I have to kill the process.
Is this a known problem, and are there any workarounds?
Leaving the calibration off gives very pink images, that aren't really usable.
If you need further information, just ask.
Thanks,
