All, I downloaded the latest git snapshot of the sane backend (1.0.25git) and built it from source according to the instructions in README and README.linux. Everything went smoothly until I got to the point of trying 'scanimage -L'. What I don't understand (and would like help with) is why sane-find-scanner will find my scanner (with or without root), but scanimage -L will not (with or without root).
When I was using the 1.0.23 distribution from yum repos, I was able to get the scanner recognized by both of these commands (but the my scanner wasn't supported at all by that version). Now I can only get sane-find-scanner to recognize my scanner.
