I recently acquired a scanner (Canon Lide 220). Although it is listed as supported by Sane (http://www.sane-project.org/sane-mfgs.html#Z-CANON), I wasn't able to get it working.
I followed the advice posted in SANE Support for Canon LiDE 220? , compiling Sane from sources, to no avail.
sane-find-scanner quickly finds the scanner. But
sudo scanimage -L does not recognize anything.
Then I noticed that the version of the backend (genesys-1.0-63) listed by the sane project is higher than the one just compiled (genesys-1.0.26). Or isn't?
How can I gather/compile the last version?
I realize that there exist a similar question, with answers, but I'm not in a position to suggest an answer, and I do not have enough credits to add my question as a comment.
Just in case it matters, I'm using Ubuntu 14.04.
