Sorry for confusion. What I meant was, that libfprint and pam_fprint compile and start clean. Also the device gets properly detected and scans the fingers e.g. in fprint_demo. My problem was I could not verify a fingerprint against an enrolled one, but I was just testing around again and experienced that the matches are pretty good when using exactly the middle of the fingertip (where the most "curls" are). > Anyway, if you're having false rejection issues, then you should look at > the images and examine their appearance.

Thanks for the hints - I get definetly more minutiae counts when using the fingertip more centered on the reader - I think therefore the matches are also getting better.
