I'm currently helping a new(bie) Linux (Ubuntu) user to migrate from Win to
All works fine except his LiDE100.
Someone told me to add gnomescan after having upgraded to Ubuntu Jaunty,
that's what I did, but unfortunately that didn't helped for the Canoscan;
see the test output:

# sane-find-scanner will now attempt to detect your scanner. If the
# result is different from what you expected, first make sure your
# scanner is powered up and properly connected to your computer.
# No SCSI scanners found. If you expected something different, make sure that
# you have loaded a kernel SCSI driver for your SCSI adapter.
found USB scanner (vendor=0x04a9 [Canon], product=0x1904 [CanoScan], chip=GL843) at libusb:001:003
found USB scanner (vendor=0x06b0 [ALVA B.V.], product=0x0001 [ALVA 544Satellite]) at libusb:003:004
(note: ALVA is NOT a scanner but my USB braille-display :-) I need it for
being able to help that person since he's sighted and I'm not ! )
# Your USB scanner was (probably) detected. It may or may not be supported by
# SANE. Try scanimage -L and read the backend's manpage.
# Not checking for parallel port scanners.
# Most Scanners connected to the parallel port or other proprietary ports
# can't be detected by this program.
root at ubuntu:~# 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).

Why isn't it possible to emulate a LiDE20 or 25 or so with another LiDE like
the 100 ? he's scanning only papers, not pictures, so he only needs grey and
for text purposes.
Another problem is that the model 100 is from 2008, and I can't advise him
to drop it on the trash and buy another ...
Which Canon people should I contact to ask for info so that a driver can be
made ? what kind of info is needed to build a driver for a scanner ?
On the other hand, which other comparable product from another manufacturer
should he buy in teh future ? he needs a small scanner and the LiDE series
are very very compact, that still make them attractive...
