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.
