The line was missing , I added it.
Now it shows up in the list:

So now I 'm back to the original condition, where I'm getting this:
Why would I be getting the message:

when I added it to the source file,

I also have to thank for this patch (it came on the day I boght the scanner
without knowing about the issues). It is almost perfect as it works nice for
resolutions up to 1200 dpi. At 2400 and 3200 I get a combing effect. Every
other pixel column is offset by several pixels. It looks a bit like an
interlaced PAL TV picture (only the combing is vertical rather than
horizontal).
Hints appreciated (also if someone could confirm this. The error isn't there
in windoze, so it doesn't seem to be a hardware problem).
Some final questions:
- Is there any way to make use of the buttons on the scanner? I tried
scannerbuttond, but it didn't work.
- Does scanimage/xscanimage scan with 24bit or 48bit depth? If the first is
the case, is there a way to scan with 48bit?
Cheers
Tobias
