That one is unsupported by SANE as far as we know.

Ok, so the kernel has detected it. That's ok.

Ok, but probably not necessary.

No, you don't have these choice. You (or someone else) must write a
SANE driver (backend). That backend uses either libusb or the kernel
scanner driver. So definitely need a SANE backend for every scanner.
libusb and the kernel scanner driver just provide the means to contact
the scanner. All the "intelligent" work is done in the backend.

Well, see the discussions on this list and:
