[sane-devel] New to list - need help to understand sane

[William Heidrich]

Hi,

I'm trying to configure a canon fb630u.

running xsane canon630u

I get: failed to open device - invalid argument

I've included some of the logs below.

If there are any suggestions. Also, how do I connect the canon630u.conf
file to sane?


Much appreciated
