[sane-devel] sane + ubuntu 14.04 + Epson perfection 3170

Sat Nov 15 11:44:36 UTC 2014

Hi Pierre,

Seems like we know each other :-) It's a small world after all !

Did you try the GIT version to see if it corrects your problem ? Feel 
free to send me a mail (in French of course) if you need help on that.

Bye.
