My first post to this mailing list... I have a Visioneer 4800 USB (vendor=0x04a7, product=0x0224). It is currently unsupported (http://www.sane-project.org/unsupported/visioneer-onetouch4800.html). The experimental backend hp_rts88xx may be a step in the right direction (Realtek RTS8801B chipset), but does not support this scanner in particular. I don't have access to a Windows computer to do usb snooping with. Since the scanner is useless to me, are there any backend developers out there who would work on support if I sent the scanner to you?
