Hi Rob,
No, sorry, I am not involved in this anymore, I was trying to find devices
that use a known pixma protocol, but that is not the case for the above
scanners. You'll need to check the mailing list archives for separate
threads on these scanners, if there are any, or start your own with USB
sniffing. Genesys backend development is very lively, so if your scanner has
such a chip, it is likely you will be roped in to help with support pretty
Best regards,
