The biggest problem usually is to find out which protocol the scanner
speaks. If you can't get a detailed protocol description from the
manufacturer (unlikely), you'll have to "sniff" the USb connection
under Windows. Some links:
When you have gathered some protocoll data, try to understand what's
going on. E.g. which series of transfers moves the scan head to the
beginning and how to scan in gray mode.
Concerning programming on Linux: a compiler (gcc), an editor, some
libraries like libusb and the SANE source code will be enough.
I recommend to start with wroting a simple C program that uses
sanei/sanei_usb.c to wrire some stuff to the scanner and read the
sanei_usb is documented here:
And please inform us about what you do. If possible, set up a website
with all the information you find so others can help or use the
