Re: Getting a Canon scanner to work

[Petr Janda <elekktretterr@xxxxxxxxxxxxxx>]

Ok, Ive done more progress. I forgot to use Walt's patched 
sane-backends. Now I did it, and scanimage -L finally recognizes the 
scanner.

Now Ive got 2 questions:

1) It only works when Im logged in as root, non-root still cannot find 
scanner, what did you do to get yours working as non-root Walt?
2) How do I make a patch so I can send it to submit? I only have one 
source tree at /usr/src

Cheers,
