I've tried the above procedure several times over the past weeks, and I
can't get it right. The ubuntu sane-backends package is missing the
.changes files, etc. 

Also, I'm missing the punchline of the procedure, I want to make a new
.deb that I can dpkg install on any number of machines, report upstream
that the patches help.

I'd like to do the hardware testing on the patch, since it's a relatively
uncommon scanner, and the patch seems like it will make this hardware
usable on Ubuntu.

Can anyone with ubuntu-flavored dpkg-fu either list a working procedure,
or post a deb with the patches integrated? Any info would be much
appreciated.

Thanks,
Jeff
