[sane-devel] Agfa Snapscan 1212U, with SANE, on El Capitan

[Niels Hutchison]

OK. Next step...

1. I tried SwingSane, a Java frontend for SANE:
https://sourceforge.net/projects/swingsane/files/releases/0.2/macosx/
First step seemed to be configuring Global Settings, naming
Resource/Username/Password. This should identify the scanner
(according to the enigmatic video). I used "snapscan"/User name &
password for my home folder, then several other combinations. But
nothing turned up & no scan could be made. Here is the relavent
system.log (I think):

2. I also tried SaneScanner, Alex Scheider’s app for OSX 10.7 and newer.
https://www.dropbox.com/s/bjbnye7uj6egxrx/SaneScanner.zip?dl=1
It recognized an "Agfa snapscan". When the scan button was pressed, it
went through the motions - an animated logo and tick on scan
completion - but no scan was made and the scanner did not move. Here
is the system.log:

--------------------------------
The "excessive wakeups" seem a bit of a worry...
As usual, no scan could be made with Image Capture, Preview or GIMP.
Other apps (QuiteInsane & WebSANE) seemed too complicated for me to
install.

I'm running out of clues.
Any ideas?
