Thanks for the help. I found the problem... installed udev was version
111, which apparently creates the devices in the /dev/bus/usb directory,
but not with the %03d/%03d format as expected by Sane
(which looks for /dev/bus/usb/002/002-like devices)

I compiled and installed udev 140, which caused a couple of other
headaches, but the devices were now correct in /dev/bus/usb. All is
working correctly now. And I learned a lot about udev too, ;-)
