Hello everybody,
I recently purchased a Canon CanoScan LiDE 500F (not a 5000F). Trimmed
out put of "sane-find-scanner -v -v" and the appropriate part
of /proc/bus/usb/devices. The scanner seems to have a GL841 chipset.
I have downloaded the cvs code for sane-backends and experimental trees.
I have also scoured the mailing list for all posts relating to the
development of support for this chipset. I have 2 questions -
1) Should I be looking at genesys or genesys-new?
2) What can I do to help? (I am happy to help write code, I do not
have windows installed so I am no help
when it comes to sniffing successful
windows scans)
I am eager to help with this effort and due to medical circumstances
have alot of time on my hands, please put my meagre talents to use :)
