Did the above but gpsd is not running.
No orphaned TCP port 2947, though.

Did this too (changed to ttyUSB0 and 4800 baud as shown above)

After the reboot there is this response:
address@hidden:~ $ cgps -s
cgps: no gpsd running or network error: -6, can't connect to host/port
pair

So then I tried this to start gpsd service:
 sudo systemctl start gpsd

There was no error message or such but the netstat did not show any
port listening and the command line response was the same.

Finally I edited the /etc/default/gpsd and entered ttyUSB0 as a device
to check.
Rebooted and waited a while.
Now gpsd is running and there is a TCP port listed so it should work.

But cgps -s just shows an empty screen with no data until it times
out.

I even tested:
 sudo systemctl stop gpsd
 sudo systemctl start gpsd

Same result..

Finally:
sudo systemctl stop gpsd
sudo gpsd /dev/ttyUSB0 -F /var/run/gpsd.sock

Now by manually starting the daemon it works and cgps -s displays
running data.

So it seems like gpsd will not work properly on boot for me but will
work when I manually start it......

This is what I have in the files mentioned above:
/etc/default/gpsd:
------------------
# Default settings for the gpsd init script and the hotplug wrapper.

# Start the gpsd daemon automatically at boot time
START_DAEMON="true"

# Use USB hotplugging to add new USB devices automatically to the
daemon
USBAUTO="true"

# Devices gpsd should collect to at boot time.
# They need to be read/writeable, either by user gpsd or the group
dialout.
DEVICES="ttyUSB0"

# Other options you want to pass to gpsd
GPSD_OPTIONS=""

/etc/systemd/system/gpsd_settty.service:
-----------------------------------------
[Unit]
Description=gpsd set initial baudrate for BU-353 GPS
Before=gpsd.service

[Service]
Type=oneshot
RemainAfterExit=yes
ExecStart=/bin/stty -F /dev/ttyUSB0 speed 4800

[Install]
WantedBy=gpsd.service

Any suggestions?
