Ready to develop backend for Brother DSmobile 700D

[RayJ]

Joining the list to begin the process of developing a backend for an unlisted scanner.

Brother DSmobile 700D

http://www.brother-usa.com/Scanners/ModelDetail/24/ds700d

I am a competent C programmer. ;)

Any advice and/or direction is appreciated.

Here is the output of: sudo sane-find-scanner -v -v

This is sane-find-scanner from sane-backends 1.0.22

  # sane-find-scanner will now attempt to detect your scanner. If the
  # result is different from what you expected, first make sure your
  # scanner is powered up and properly connected to your computer.

     Hello,

     since it is a genesys chip, i could be added to the genesys
backend. GL848 ASIC isn't supported yet. I have recently added code for
GL846, so it could give you an idea of the work to be done. Only GL646
and GL841 sheet fed scanners are  supported, so you'll have to look
these sources to see what is required for a sheet fed scanner.

     I think it is worth double-checking that it is really a GL848.
sane-find-scanner heuristic is not bullet proof. Ideally seeing the chip
inside would definitively tell us, but this can be inferred by analyzing
USB logs of the scanner run under windows, and comparing values for the
few registers that are different between the GL846 and the GL846.

    Hello,

    so it is a GL125. Another ASIC needs to be added to the genesys backend. There is already support for GL124, but this one doesn't support any sheet fed scanner yet. GL841/GL646 are still the source of inspiration for shet fed only functions, while you may quick-start your work with GL124 code.

Regards,
    Stef

Excellent. I will start with the GL124 and use GL841/GL646 for as a guide (for the sheet fed functions and logic.).

Thanks!

Oh well.

Scanner is broken. Something I did while taking it apart.
