[sane-devel] Hello & Visioneer Onetouch 4400 USB Scanner
Sun, 30 Nov 2003 13:15:15 +0100
I'm pretty shure, that the Visioneer 4400 does not contain a LM983x ASIC.
I checked some logs in spring this year, and there it turned out to be a
GeneSysLogic based device, at least containing a GL 640 bridge. The
ASIC is unknown to me, probably one of those E... ones - maybe Steven
Ellis knows more...

It should be enough to know how to write good C-programs, controlling
USB devices is not that complicated. The more complicated thing is
figuring out what to send and how to interpret the messages/commands
between scanner and your box...

Probably not :-(
