[sane-devel] Neat ND-1000 GL843 Genesys Scanner Support

I have been attempting to get the Neat ND-1000 scanner to work on Linux.
I've spent a few hours researching and it appears that while this scanner
is not on the supported scanners list, it seems like its very likely to
work with little effort.

I attempted to pull the current backends master tree to hack and rebuild to
see if I could get it going, but I'm not having any luck in my build
environment (Debian 10) - probably missing a bunch of stuff required to
build. I went a few rounds installing some missing packages but still not
making any real progress. Debian 10 is using 1.0.27, and after perusing the
codebase on gitlab, the master branch appears to be significantly different
for the genesys backend and possibly even a rewrite(?).

At any rate, sane-find-scanner returns the following:

found USB scanner (vendor=0x1f44 [The Neat Company], product=0x0050 [Neat
ADF Scanner]) at libusb:001:006

Scanimage -L won't return the scanner, and returns the following relevant
lines on debug (SANE_DEBUG_DLL=128 SANE_DEBUG_GENESYS=128
SANE_DEBUG_SANEI_USB=128 scanimage -L):

I have already added the following line to /etc/sane.d/gensys.conf:

# Neat ND-1000
usb 0x1f44 0x0050

I have also ensured that saned is not masked by systemd, enabled, started,
restarted, etc.

It looks to me that this message:

"[genesys] attach: vendor 8004 product 80 is not supported by this backend"

Indicates that the code does not recognize the Neat ND-1000's USB VendorID
and ProductID. It seems that adding that info to backends/genesys_devices.c
with a reference to a similar scanner may get it to work.

I would try adding these into the codebase and compiling myself, but as I
said, I didn't figure out a working build environment. Any thoughts on
getting this to work?
