Hi everyone, about Canon FS4000US USB/SCSI film/diapos scanner
First, it works fine with Vuescan but with scsi only. Vuescan is a good software, so I decided to purchase a (pro) licence. And so I'll be able to test new unsupported scanners with it, to find information if I can. But, I want to see this scanner working with free software under Linux, with my favorite Gimp, and under the usb bus... I've found a documentation about USB implementation, and I have begin to work. So, a driver is not for today :-) Secondly, ... I've opened the machine :-) If someone is interested with the chips references I found inside, see above : CARD Z919-03 Main Other references found : YH1-0776 YG7-0139-03 [25G] The biggest chipset is (more than 200 pins) : Canon Kikka YH4-0201 0214 Z24 Another one : Malaysia 29F400TC-90PFTN 0208F59S The next one : 0212EAI TMP95C265F F0025ZAE Japan Again : RONALDO # nice name...:-) FH4-6069 T6W93B-0002 Japan 0206EAI D0078AAA And the last one : LSI LSA0002 CF92A Y0204 WPE04020 *or* WPD4020 (not sure) Hope this help (?) If someone can recognize something interessant, let me know... Thirdly, I've read the thread about HP4200, and I have the same 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) Thank you Best regards -- NO ePATENTS / NON AUX BREVETS SUR LES LOGICIELS.
