Thomas,

Success!  I have found two places in the code where this commenting out nee=
ds=20
to be done. After that things worked really well.

I used xsane to preview.=20
I scanned at 75dpi,300dpi,600dpi and 1200dpi

Only problem was that the image was a little blue. I had to up the brightne=
ss=20
to about 50 to get "white"

This makes me VERY happy to see this working and I appreciate all your work=
=2E=20
The only thing I have left that needs windows is my camera now.. And the=20
gphoto team is working on that.=20
