I bought this device from Amazon to use for a project with a Raspberry Pi Zero and a data sim from my Google Fi Account where I wanted network connectivity. The fact that it had GPS as well was a bonus.
I installed gpsd on raspian. (apt install gpsd gpsd-clients -y) It didn’t automatically recognize the GPS. I was able to get it working by modifying /etc/default/gpsd to have the line DEVICES=”/dev/ttyUSB1″ and then starting the GPS with the command echo AT+CGPS=1 >/dev/ttyUSB2
After that combination, running gpsmon or cgps returned results after the GPS had been able to achieve a fix.
I’ve still not got it automatically starting the GPS with the echo command and am working to figure the best place to have that command.
