Hi, 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...

The more complicated thing is figuring out what to send and how to interpret the messages/commands between scanner and your box... > > Before I start hassling manufacturers, etc, is anyone else writing a > backend for this device? Probably not :-( Ciao, Gerhard
