[sane-devel] trying Canon DR-3080C

| Go ahead and try it with the current version, and see if that works.

Thanks for the clear and effective recipe.  (I had already rebuilt the
Ubuntu libsane package from source so a lot of the prerequisites were
already in place.)

When I run the new code, I get farther but not far enough.

(It seemed as if the scanner had to be on at boot time.  I guess
hot-plugging doesn't work for SCSI.)

I got the same "cannot get requested buffer size" as before but that
didn't stop the driver.  Lots of promising logging.  But in the end,
the driver didn't recognize the scanner.

Here's the log:
