Well, I uninstalled Sane, then downloaded the latest Sane backend and frontend snapshots and compiled them:
http://www.sane-project.org/snapshots/
The man page says that the Canon Lide 100 is supported:
$ man sane-genesys
Canon LiDE 35/40/50/60/100/110/200/210
However, the scanner is not detected properly.
This test finds it:
$ sane-find-scanner
found USB scanner (vendor=0x04a9, product=0x1904, chip=GL847?) at libusb:001:008
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
and this test doesn't:
$ scanimage -L
No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
and xcanimage doesn't either:
$ xscanimage
[xscanimage] No scanners were identified. If you were expecting something
different, check that the scanner is plugged in, turned on and
detected by sane-find-scanner (if appropriate). Please read
the documentation which came with this software (README, FAQ,
manpages).
Bah, humbug...
