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.
