[sane-devel] convert standalone programa to backend

[Miguel]

I've working with the kodak i1320, making a standalone program to
scan, based on sniffing the usb port.
In the actual state the program scans and saves the images (both
sides), at the same speed than in windows, and the next step for me is
convert it to a sane backend, using sane-usb.

here is where i need some help.
How do i include the .c and .h files in the makefile?
Which sane headers should i include?
Do i have to modify any where else in sane?
i have some questions on using sane-usb, mainly regarding the attach
function callback.
I can provide the source for the scanning program, if you think it is
useful, and i have the intention to submit the backend to the sane
project.

Your help will be greatly appreciated
