I can't find the datasheet for this chip, so I can't really tell
how different it is from already supported genesys chip. But even with
the datasheet, it is not convenient to develop without a test scanner. A
few seconds test can turn in a few hours (even days) long, because of
getting code changes applied remotely, then executed and getting debug
information back. Programming for these scanner involve quite a lot of
trial and error, even if you have the datasheet.
However, you can still post an usb snoop log of a color preview
scan, just to get some idea on how this scanner work.
