Hmmm, no very nice ;)

What about xsane? Same problems! I suspect xscanimage is more or less
buggy!

CVS is the versioning system where we keep track of changes and where
we keep the sources. Here you'll find the bleeding edge of SANE.
You will also find daily-snapshots at http://www.sane-project.org/snapshots/
they should contain also more or less current sources (with a delay of at least
one day)

Yep! Try 
chmow a+rw /dev/.static/dev/parport0

So keep the maschism and try to compile SANE from source, install it
and see if the plustek_pp stuff works better.
