Subject: Permission Error When Opening gpsd For XTRX Device

Hello all,

I'm trying to set up gpsd to read data from the onboard gps that the XTRX radio provides.
In the devices list, it is listed as /dev/ttyXTRX0.
I can read data from this device using:
stty -F /dev/ttyXTRX0 speed 9600 && cat /dev/ttyXTRX0.

The error I'm getting is this:
sail@gr110:~/Desktop$ sudo gpsd -n -N -D5 -S 3900 /dev/ttyXTRX0
gpsd:INFO: launching (Version 3.20)

gpsd:INFO: SER: opening GPS data source type 2 at '/dev/ttyXTRX0'
gpsd:ERROR: SER: device open of /dev/ttyXTRX0 failed: Permission denied - retrying read-only
gpsd:ERROR: SER: read-only device open of /dev/ttyXTRX0 failed: Permission denied
gpsd:ERROR: initial GPS device /dev/ttyXTRX0 open failed
gpsd:ERROR: can't run with neither control socket nor devices open

This error doesn't make sense to me as I've checked that the user and gpsd are both in the dialout group.
If I can read the data from the device, why can't gpsd open it?

Thanks for any suggestions on how to fix this or anything pointing me in the right direction.
