This may well be of interest to all those using the USB sniff program under
Windows to reverse engineer their scanners as well.
The interesting thing is that the difficulty in reverse engineering a
scanner driver protocol appears to be directly related to the difficulty
in sniffing the protocol. For parallel port scanners this was always hard
as they tend to hit the hardware directly. The shift to USB, and the
development of the USB sniff program for Windows has made sniffing the
protocol for USB scanners in comparison trivial. As a result SANE backends
have started popping up.
