Better use a backend that is already finished. For understanding how a backend works in principle, you could also look at the "test" backend. It contains an implementation of (nearly) all features SANE provides. And you don't need a scanner to try how it works. > Which of the usb backends on that page would serve as a good example to > write a backend? I read the status, but I am confused. I think gt68xx is ok for that. _low.c contains the low level stuff (calling firmware "functions"). _mid.c is used for converting the scan data from the scanner's format to something SANE can use. _high.c conatins all the "intelligent" code that does calibration and actual scanning. gt68xx.c is the SANE interface. > I guess I need to set cvs up on my home machine (which has debian woody) > and get a user login.

Otherwise you can either download a CVS snapshot (updated daily) or use anonymous CVS. You only need an account (and be added to the project) if you want to WRITE to our CVS tree. Bye, Henning
