>I have an Epson Perfection V10 scanner. I installed iscan drivers from the downloaded file iscan-gt-s600-bundle-1.0.0.x64.rpm.tar.gz on openSUSE 13.1 64 bit. It went smoothly and the scanner works with sane and xsane. In xsane I can only choose resolutions 133 200 400 600 800 1200 etc. I would expect 100 and 300 on the list too. scanimage --help -d epkowa doesn't list there resolutions either:

I have tried Epson's iscan utility. It offers the following resolutions for the scanner:
50 72 96 150 200 240 300 360 400 600 720 800 1200 1600 2400 3200 4800 6400 9600

Sane/xsane offers only these resolutions:
133 200 400 600 800 1200 1600 3200.

Not only that sane offers less resolution options but it also offers some which is not on the iscan list: 133.

Where does sane get the resolutions for the scanner?  I guess the resolutions are specified by sane and not by the proprietary Epson drivers or else iscan wouldn't show them either.

I wouldn't mind building sane from sources if I knew what to edit or change.

Any help would be appreciated.
