[sane-devel] Intend to write driver(s)

[Robert Brijder]

Hello,

I have the following two scanners.

* Compeye Simplex 1236C,
  Interface: Parport USB.
  USB id: 0x05cb/0x1483
* Primax Colorado USB 19200,
  Interface: USB,
  USB id: 0x0461/0x0360

The first one is mentioned on the sane website as unsupported, the
second one is not mentioned at all. The output of sane-find-scanner -v
-v with the second scanner connected is show below. My question is,
which scanner would be most easy to write a driver for (I would guess
the first one)? I would then try to write a driver for that one first.

BTW: I have never before written a driver, however I can write in C
and I have read the SANE standard.

Thanks,
Robert
