three different backends? the cvs & penguin-breeder one are the same but
different version... but which is the third?

Yes, I added those defines to have some point to start when some day
there would be support for this scanner.

there were somebody working on this, but i have lost track of him/her
and never heard of a success story

that would be me then...

actually, we came to the most interesting part here... and it's nearly
