1. I've build git version with setting GL846 chipset to 3600 clone in the model description. It gives the same result as I wrote before 2. In 1.0.22 GL847 worked for me well. It stopped working in 1.0.23. So I think this is not an chipset issue.

I've tried... scanimage -L does not list scanner at all in this case O_o Very strange for me... :-((( > Since having the ASIC datasheet isn't enough( GPIO, fontend, motors > > change from one model to another and are not coverd by this > documentation), the process to reach full support is to run the > experimental backend and compare debugging output with USB logs recorder > under windows, and tweak the code until it works.
