That's cool! I guess you already found the pages about starting to write a backend but just in case you haven't: http://www.sane-project.org/contrib.html http://www.meier-geinitz.de/sane/misc/develop.html > Has anybody tried to contact Mustek about technical documentation and > tried to get help from? I haven't asked about that scanner but when I worked on the mustek_usb backend I got quite some information from them. Try asking Tom Wang <tom.wang at mustek.com.tw>. I haven't talked to him for quite some time, however. > What about ALI Corporation?<br> No idea. It doesn't harm to ask. Maybe you should point to our manufacturers page: http://www.sane-project.org/manufacturers.html If you like to find out if there are other scanners using that chip, it may help to add support to sane-find-scanner to detect the chip. See the code in tools/check-usb-scanner.c. Bye, Henning
