Hi,
Attached are patches that makes scanning work with sane, using an Agfa
Snapscan 1212U USB scanner for me. They are merely reworked from PRs
32652 and 32653 by ebakke@trolltech.com.
NB: Only tested in 4.5-stable, not in -current (sorry). Patches should
apply cleanly in -stable.
It would be nice if more people could have a look at this, so that we
can get hopefully get it in the tree sometime soon.
Thanks.

Anders.
