You should file a bug report with them over the bad ID string.

And then you restarted gpsd how?  Details matter.

We are not looking for a big obvious change problem.  And sending the
whole thing in is a lot easier than teaching you to debug.

gpsd is not running at all, so nothing to debug.

We can't debug gpsd, unless you actually run gpsd.

Did you try to run gpsd?  If so, how did you try to run gpsd?

I suggest you, as root, start gpsd this way:

        gpsd -n /dev/ttyACM1

Wait 3 seconds, then see if that worked:
