Thanks for confirming, I will add a line about this when applying! I
guess I can take your response as an ack, if not please let me know.

I have obviously done some research myself and the short story is that
the elandigitalsystem went out just a couple of years after this.

The driver itself has been dead from a maintenance point of view,
which in principle happened just after the first initial commit in
2011.

Arnd, thanks for the update!
