I have a GPS receiver connected over USB that, when GPSD boots, has the SHM timing interface as 0 (ntpshmmon puts out NTP0 as the source). However, when I unplug and replug the device, Iget SHM 2 (ntpshmmon puts out NTP2). All future replugs are at NTP2.

How can I get GPSD to stay consistent with the SHM it writes to? I only have one receiver attached.
Does this happen even after a restart of GPSD? My thinking would be that if GPSD is running at the time you unplug, GPSD may consider SHM0 still in use, so then it assigns it to the next available SHM interface (SHM1 being already reserved for PPS1?)

Just a thought.
