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.
