Not too sure if how similar the Visioneer 4400 is to the 8000 series scan= ners,=20 but a backend (supposedly) exists for 8000 series, at least some of them.= I=20 have the source for the 8000 series backend and am expecting an 8920 in t= he=20 mail within the next month. At that time I was expecting that I would hav= e to=20 work on the source that I have to adapt it to the 8920. If the 4400 is=20 similar, then we can combine our efforts. I will be connecting via USB 2.= 0.
If you think the source I have will be helpul, I can send it to you.
