[sane-devel] Fix 45-libsane.rules to support Epson V100

[Stephane Blondon]

I have got a scanner Epson Perfection Photo V100 (which need the
proprietary driver Epowka). I have installed it and it works only with
root: xsane don't find the scanner when launched with the classical
users accounts (tested with two).

I have found that the scanner is not included in
/etc/udev/rules.d/45-libsane.rules.
I have added it and now it works well. A 'diff -u' of the change is
joined to this mail.
Note that I only do a reference to the 'Epson Perfection V100' in the
diff. It seems that the V10 is globally equivalent (due to same driver
and the answer of scanimage) but I don't know if they have the same
Product ID.


If you have questions or comments, please cc me because I have not
subscribed to the ml.

Stephane.

No scanners were identified. If you were expecting something different,
check that the scanner is plugged in, turned on and detected by the
sane-find-scanner tool (if appropriate). Please read the documentation
which came with this software (README, FAQ, manpages).
