What this implies  is that the network code can find the scanner, but
the actual backend does not recognize it. Are you sure that the same
backend is installed? It looks as if you compiled your own version on
the desktop, but not on the laptop?

If uou have git commit access you could do that I guess. It is probably
better if the current maintainer of the backend (Nicolas, Gernot?) does
that, the changes do not affect any other devices, so I can not see a
reason not commit.
