I've added the information you provided to our lists, see http://www.meier-geinitz.de/sane/misc/canon-fs4000.html. When you have a website or other location where you place information/logs/source code for this scanner, I'll add a link to it. > If someone is interested with the chips references I found inside, see > above : > Malaysia > 29F400TC-90PFTN > 0208F59S I think that's an EPROM or EEPROM or similar.

Google has some information. > I've read the thread about HP4200, and I have the same problem... It detects every scanner as a USB device. But as you want to develop a new backend, you should use the SANE CVS anyway: http://sane.alioth.debian.org/ SANE doesn't include the hp4200 backend, so there is no problem :-) > Finally, I've got a question : where can I find an example of backend ? > For example, there is a file called usb-skeleton.c in > /usr/src/linux/drivers/usb, but what for sane-backends (found nothing in > sane-backend-cvs-snapshot) Well, you have about 50 examples in CVS :-) It doesn't really make much sense to write a template because the backends are quite different. Most of the shared code is already in the sanei functions. In your case, I'd have a look at one of the SCSI backends first, at least if the scanner is really SCSI-over-USB. What you really need for the beginning is to copy all the sane_* functions to your new backend. Everything else depends on you :-) Bye, Henning
