I had try again with git last version.
I just compile a sane-backends ( git clone git://anonscm.debian.org/sane/sane-
backends.git) and modify the file pixma_mp150.c to add support for the Canon 
MG8150 printer.

sane-find-scanner found the scanner on USB mode

But after:

Scanimage (from /usr/local/bin) has no verbose mode, with -v or no, I just has 
the msg "scanimage: no SANE devices found" 

Have you and idée ?


If I success to have the Canon MG8150 to work, can i commit that to git  to 
give the driver for this printer to all the community ? (And after that on 
each linux distribution ?)

Thanks.
