pour ce qui est de xsane
j’ai upgradé libsane en version experimental https://packages.debian.org/fr/experimental/libsane
pour satisfaire les dépendances j’ai téléchargé
@desktop:~/canon$ ls *.deb
libgphoto2-port12_2.5.10-2_i386.deb
libltdl7_2.4.6-0.1_i386.deb
libsane_1.0.26-git20151121-1_i386.deb
libsane-common_1.0.26-git20151121-1_all.deb
sane-utils_1.0.26-git20151121-1_i386.deb
installé avec sudo dpkg -i *.deb
Et maintenant la Canon Pixma MG3650 est détectée
canon# sane-find-scanner
# 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.

# 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.
