Hi Walt.

I see that our scanners vender and product ID is hard coded in the
uscanner.c in the 1.12 release.

I will compile a new kernel and try it.  The 1.10 release shows a small
set of supported scanners.  Did you compile sane-backends *without libusb*

I didn't change or configure anything when building sane-backends or libusb,

Because the sane-usb manual says to remove any kernel usb scanner driver
in order to use it.
I had to do that in NetBSD but not DragonFly.
