The hp4200 (LM9830 + PV9830) and the umax1220u (.. +PV9830) backend)
uses the same par/usb bridge).
Your scanner probaly has inside a LM9820 and PV9830 so is different
compared with the hp4200 backend, for difference see National
Semiconductor datasheets for LM9820 and LM9830.
If there is already a backend which uses a LM9820 i don't know?
