you did not say which version of sane. there was a bug in scanimage that caused problems with some ADF scanners, which was fixed in sane 1.0.18.

Also I didn't see earlier messages in this thread so apologies if I cover old ground.

Don't worry: we all started somewhere and I doubt that many SANE contributors (maybe none?) do so as part of their jobs. You can find information about the process of writing a SANE backend at http://www.sane-project.org/contrib.html Time and patience will certainly be required. > I have no idea if it is enough to switch on some sane logging and compare > the output wiith the logs from windows, or is there a need do disassemble > the scanner to get a knowledge of the electrical components.

Get scanner working under Windows 2. Use a USB snooping tool to obtain USB traffic between computer and scanner whilst performing a one or more scans on Windows. 3. Stare at the captured data and try to make sense of it. You might be able to get clues by comparing with the other backend source code. Also if you have queries about the interpretation of specific messages then posting those questions to sane-devel is more likely to receive answers than general inquiries. 4. Determine whether a new backend is required or whether modifying an existing one will suffice. 5. Do it :-) Good luck! cheers, Jon -- ====================== Jon Chambers ===================== http://www.jon.demon.co.uk, 020 8575 7097, 07931 961669 =========================================================
