It slightly sounds to me like you are probably mixing up 
GPS-device-file(dev/gps) and /usr/sbin/gpsd. You need a seperate Daemon 
called gpsd (to connect to. This Daemon itself then connects to your 
gps-device-file which itself is connected to your GPS by the kernel..
The old GpsDrive versions had direct connection inside AND had an automatic 
gpsd strting mechanism. This is no longer inside GpsDrive and has to be 
configured/started by the system outside gpsdrive.


If you are doing

and getting "no connection", you either have gpsd not running or it's 
configured different than you thougt.
