I'm not nearly that far. I'm still staring at usb logs when I have the time.

I do have a "magical incantation" (usb playback) that results in a
scanned image, but I don't know much about what the commands actually
do. It seems like the SQ chip in the HP4600 is very similar to the
chip for the mustekusb2 backend, so I've been using that code to
decipher some of the commands. I'll need to become much more familiar
with the mustek code in order to figure out the differences between
the two.
