How can I automatically launch GPSD on startup?
I am trying to figure out, what is preventing gpsd from automatically connecting to an external GPS BU 353 dongle via USB and receiving data. I have the same issue on both of my laptops (with different hardware), so this is purely a software configuration issue.
I have managed to get gpsd working manually, using the following steps, but every time my machine is powered off, I must go through these steps again.
sudo killall gpsd
Remove any sockets
gpsdmight have left behind with :
sudo rm /var/run/gpsd.sock
Check the device path:
dmesg - which shows PLU353
Ensure no other programs are using the device. There are none listed
lsof -n | grep /dev/ttyUSB0
Manually launch
gpsd:
sudo gpsd /dev/ttyUSB0 -F /var/run/gpsd.sock
xgpssees the GPS output - so this works
My best guesses are that gpsd needs to join a group or be given additional permissions, or alternatively, that it is an issue with udev configuration. But I am blundering about in the dark, just making wild guesses.

You're correct - it is a group membership problem. First, see who owns the device:
ls -l /dev/ttyUSB0
On MY system, I don't have /dev/ttyUSB0, so I'll use /dev/ttyS0 instead
walt@bat:~(0)$ ls -l /dev/ttyS0
crw-rw---- 1 root dialout 4, 64 Feb 23 08:19 /dev/ttyS0
walt@bat:~(0)$
The output of the ls command shows that it's owned by root:dialout, and allows group access to the device.
Add your user to the dialout (or whatever is right for your system) group with:
sudo adduser $USER dialout
Then to make this group membership take effect, logout/login, OR newgrp dialout to start a shell with that group membership.
Check your group membership with /usr/bin/id.

- open TCP port 2947 in your firewall (if you wish other network clients access)
- make sure your username is in group dialout
- in
terminal, edit/etc/default/gpsd
sudo -H gedit /etc/default/gpsd# edit the gpsd settings file- change
DEVICES=""toDEVICES="/dev/ttyUSB0"# /dev name may be different - save and quit gedit
sudo systemctl restart gpsd# restart gpsd
gpsmon, cgps, and xgps will now work properly.

No, not unless you have modified/etc/ufw/before.rules, which by default allows all onlointerface. In addition, it should be noted that gpsd may use a socket as well, which does not touch the network stack at all. As I stated; in the question it works after restarting gpsd, without any modification to the firewall rules.

@vidarlo ok... educate me... where is there any documentation about modifying/etc/ufw/before.rules, and what would you modify there? Also, re: tcp port... "Client applications will communicate with gpsd via a TCP/IP port, 2947 by default)".

No, not unless you have modified
/etc/ufw/before.rules, which by default allows all on lo interface. In addition, it should be noted that gpsd may use a socket as well, which does not touch the network stack at all. As I stated; in the question it works after restarting gpsd, without any modification to the firewall rules.– vidarlo

@vidarlo ok... educate me... where is there any documentation about modifying
/etc/ufw/before.rules, and what would you modify there? Also, re: tcp port... "Client applications will communicate with gpsd via a TCP/IP port, 2947 by default)".– heynnema
