i have been in communication with canon for months to get the
interface docs for the DR series. they are quite slow, i dont know if
it will ever happen, because their legal dept. is concerned about the
source code being released. this morning, i had a long conversation
with a member of their US staff, who is working to get some of the
docs in my hands. Even when i get the docs, i will not have much time
for volunteer programming work, as i dont have or need one of these
machines. so why am i trying to get the docs? 'because it was there'
:)

but, the scanners are scsi, so they should use a reasonable protocol.
it should be possible to copy one of the existing scsi/usb backends
(say, fujitsu) and modify it to work.

without docs, you will have a hard time supporting all the vendor
specific features, but basic scanning should be possible.
