Raspberry Pi and gpsd ( getting around startup bug )

I need location information for one of my Raspberry Pi devices. I have a USB GPS receiver that appears on /dev/ttyUSB0. To verify the hardware operation, I installed minicom

sudo apt-get install minicom

sudo minicom -s

Then set the port to /dev/ttyUSB0, port parameters to 4800 N8! with no flow control. You should then be able to see NMEA sentences

Once we have proved that the hardware is working, install gpsd.

sudo apt-get install gpsd

sudo dpkg-reconfigure gpsd to set the serial port

Then you have to manually edit the /etc/default/gpsd file and remove /dev/ttyUSB0 from the DEVICES and put it into GPSD_OPTIONS field.

sudo reboot

Once running, you should be able to run cgps -s to see gpsd responding with valid location information.
