[Bug 270185] Re: sane-find-scanner sees scanner, scanimage -L does not
Sorry, I've finally found the issue on my system: /etc/sane.d/snapscan.conf had
the wrong permissions. (But that's my fault, not Ubuntu's!)
Running "SANE_DEBUG_SNAPSCAN=128 scanimage -L" put me on the right track.
("configuration file not found")
