[sane-devel] Problem with Canon MX370 scanner

[Matthias Peter Walther]

Hello,

Ubuntu 14.04 still comes with backend version 1.0.23, which doesn't
support that scanner. You need to install the git version of sane.

Follow these instructions: http://www.sane-project.org/README.linux

Greetings from Germany
