[Nut-upsuser] Problems getting reading from UPS with nut 2.0.2

Problems getting reading from UPS with nut 2.0.2 Debian Sid

I know that the server starts running and accepts incoming connections, it can 
verify the username and password but refutes that the UPS lives at localhost, 
what am I doing wrong ?
I have read and reread both the official documentation and various guides 
around the net I am unsure where to go now.

If the UPS itself is at fault (not supported model) then I would have expected 
something else.

There now follows hopefully more information a than you could ever need.
(any notes that are not part of the original output have been prefixed with a 
double hash
