[sane-devel] scanimage -L detects no scanners / sane-find-scanner does -- on MacOS

[Media Mouth]

Well noting yet.  Any reason to think that using the proprietary software that comes with a Fujitsu scanner "ScanSnap.app" might do something that interferes with SANE.  (I'm suspect SANE is their underlying engine)

We are and have been able to scan using ScanSnap, and for a brief moment yesterday we were also able to run `scanimage` and save a .pnm
