![]() Sometimes it gets mounted to /dev/ttyUSB1 if 0 isn't free! If it doesn't mount, then you're missing a kernel module (from your description, that's unlikely). Check dmesg | tail -n 5 to verify the dongle was really mounted to /dev/ttyUSB0.Plug the USB dongle back in and wait 10 seconds.Wait 10 seconds for /dev/ttyUSB0 to be freed. Unplug the USB dongle and kill gpsd ( sudo pkill gpsd).Do the following steps in order to test the dongle, the kernel module, the mount, the device node, and gpsd: If there's no gpsd output, then do a more detailed check. ![]() gpsmon can help diagnose that problem, too. Restart gpsmon each time you restart gpsd.Ĭould tango be starting too soon? The dongle requires a few seconds to sort out the signals, identify satellites, and calculate a fix udev requires a few seconds to start gpsd, which in turn requires a few seconds to probe the dongle (which may not be ready yet) and begin broadcasting useful information when the data stream finally begins. Open a separate terminal window and run gpsmon (included in the 'gpsd-clients' package) to check gpsd output. Try the -b flag (for example, gpsd -b /dev/ttyUSB0)
