[sane-devel] plustek_pp not working properly for 12000P

[Brian J Densmore]

I am running a debian system with a manually compiled/installed 2.6.13 
kernel.
I've built the plustek pp kernel module and use that. Scanimage can't 
find the
scanner, unless it is specified on a -d option, or via an environment 
default scanner
setting. Scanning in only works in lineart or dithered modes. The gray 
and color modes
produce only solid black output. Perhaps this is not the right forum for 
this, but this scanner worked in Mandrake, and obviously still works 
based on the dithered images.

output of my /proc fs :

brian:~$ cat /proc/pt_drv/device0/info

brian:~$ cat /proc/pt_drv/info

----------------------------------------
Output of scanimage with a default device:

brian:~$ export SANE_DEFAULT_DEVICE=plustek_pp:/dev/pt_drv0
brian:~$ scanimage -L

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).
default device is `plustek_pp:/dev/pt_drv0'
