You're forgiven ;-)

If you built from source (or convert with alien *without* --scripts)
that is to be expected.  Image Scan! creates its own iscan.rules in
the post-installation phase (using libsane.rules as a template when
found).

Ubuntu should be getting them automatically with the next update of
their SANE packages now that Julien Blache has committed the patch to
epkowa.desc I sent a few days ago.  That files includes USB info for
all the devices supported by iscan-2.10.0.

The last update before that was iscan-2.3.0, IIRC.  Blame me.

Hope this helps,
