[sane-devel] Epson Perfection V10 missing resolutions

[Adrian]

I had a similar problem a few years ago with the Perfection V200, using
the epkowa driver.  In my case the utility I first used (can't remember
what, maybe scanimage) only offered me either 300 or some huge one. 
That was before I was on this list and I took the easy way out, used
iscan which gave a good range of resolutions.  So it seems to be a
common issue.

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:
