HP 4850 backend

[Александр Панков]

Hello!

I have got a HP Scanjet 4850 photo scanner. As far as I know, it is not supported by Sane yet, and I'm going to write a backend for it.

Anyone can help me? I have some questions.
1. Did anybody try to write 4850 backend? Why it is not supported?
2. If no... How to start?

Thanks, A.

        Hello,

        this scanner is reported to have a GL841 ASIC. If so it could be added to the
genesys backend. Try sane-find-scanner to check the ASIC. If it is really  
GL841 based, have a look at the genesys*.[ch] sources. You can start by adding
needed entries in genesys.conf.in and genesys_devices.c and then start to
tests.

Regards,
        Stef

Please let us know if you get anywhere. I have the HP 4890, which is
nearly identical.
