Canon N640P EX & Xsane don't work
 
Hi there,
I have one of these Canon N640P parallel port scanners which I cant get to work in xsane or kooka.

All sane tests pass ok using the test backend.

I have made the changes to canon_pp as in the instructions, and made sure that users have permissions on /dev/parport0 without success.

Even loggin in as root will not get the sucker to work.

Here is the ouput of scanimage -L:

john@yos ~ $ export SANE_DEBUG_CANON_PP=100
john@yos ~ $ scanimage -L
[sanei_debug] Setting debug level of canon_pp to 100.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).

**Edit**
Just found this in dmesg:

Can someone give me a clue to fixing this?

Thanks
