I just got a V500. I installed Sane. The scanner was deteced when i ran "sane-find-scanner" but not when i ran "scanimage -L". I even installed the driver from "http://www.avasys.jp/english/" even though i knew it wouldnt make a difference.

is there anything i can do?

i have 64bit xubuntu on my stationary, and regular 32bit on my laptop. i tried both with the same result.
