I analysed some USB snoopy logs of the HP5400/HP5470 and the data transfer protocol doesn't look very complicated. I wrote a simple tool that issue a command to the scanner to make it return its version string. I don't have such a scanner myself and have not looked at other commands that the scanner may accept, so a sane backend for this scanner is still far away. Bertrik
