Let me know if you have any complaints/comments/feature requests.
You'll have to get the kernel scanner driver to associate with this (as
yet unknown) USB device (until it gets built in to the kernel)

I've got my new backend working with
./configure --disable-shared
scanimage correctly finds my scanner (usb canon 630u) and scans.
But as soon as I take out the --disable-shared flag it says
lt-scanimage: no SANE devices found
Clearly I'm missing something in the setup...

Where's the right place to store a permanent calibration file (created
once per scanner)? Is there a facility for this? Looks like
hp-option.c stores one in ~/.sane/calib-hp:device, but
a) I want mine per scanner, not per user.
b) seems like this would be a common thing, so I was hoping for
Hey gang, some general questions.
Since I'm still unemployed, I figured I'd go ahead and do a SANE backend
for my scanner (Canon CanonScan fb630u, USB). I was kind of hoping I
could take an existing SANE USB backend and modify it for my purposes.
Right now, I've got a standalone scan utility t

Thinking about the calibration routine for my scanner (Canon FB630U),
seems to me this is probably a common issue.
There's a black and a white scannable area inside the housing of my
scanner. It looks like I need to convert scans of these areas under 3
different lighting conditions into the per-

Got my first image out of the Canoscan FB630U.

So I just realized that the registers I was painstakingly mapping are
simply the National LM9830 registers. Silly me. Anyhow, here's how
some of them are used in this scanner.
