Yo Leon!
  If I am reading the above paragraph correctly, it sounds like you have 
two configurations:

A)  Your desired configuration, the GPS's USB is connected to the flight 
controller.

B)  The configuration you have sent gpsdebuginfo data for, the GPS's USB 
is plugged into the Raspberry Pi's USB.

If this is the case, I believe there is no way for gpsd to connect to the 
GPS in configuration A UNLESS the flight controller passes it's connected 
GPS's USB through on it's USB connection to the Pi (highly unlikely in my 
opinion).  It is possible the flight controller may present GPS data on 
it's USB connection, but then you have to tell gpsd to connect to it, and 
it would have to output something gpsd recognized.
