Nobody? I found this old discussion which seems to suggest the pixma devices don't support auto-detection:
http://lists.alioth.debian.org/pipermail/sane-devel/2009-December/025674.html If that's indeed the case, may I suggest updating the pixma backend so that it doesn't advertise capabilities that don't exist? Also, I'd still appreciate suggestion for a scriptable approach to achieve this functionality.
