correct device, but there was a file called /etc/defaults/gpsd.default
with an other entry. I checked with
nc 192.168.0.202 2947
and got the output after having started gpsd again.

Interestingly the /etc/init.d/gpsd startscript does not get triggered when selecting
"Turn on GPS" in the power menu.
Does anyone know what action gets invoked upon selecting "Turn on GPS" ?
Is this for activating/deactivating the physical device or is the /etc/init.d/gps-hardware
start script (dummy file) being invoked?
