[gpsd-users] gpsd on Debian Jessie

gpsd is not working on Jessie, Debian 8.1.

gpsd    3.11-3          amd64
gpsd-clients    3.11-3          amd64

First, the initial command in the file TROUBLESHOOTING does work, so I
know I have a device and a device file. I use:

stty -F /dev/ttyUSB0 ispeed 4800 && cat </dev/ttyUSB0

Second, when I run

# service gpsd start

and

# service gpsd stop

my program to monitor gpsd correctly notes loosing and regaining the
connection to the daemon. xgps also dies when it looses its connection.

$ ./gnome-gps -v

xgps also reports 
"{"class":"VERSION","release":"3.11","rev":"3.11-3","proto_major":3,"proto_minor":9}"

When I plug in the GPS receiver, neither program reports any data from
it. gnome-gps should report the new device, but does not.

I then edited /etc/default/gpsd:

DEVICES="/dev/ttyUSB0"

I now get data in both programs indicating a connection with the
receiver such as the current time. I get a fix and everything looks
good.

This leaves me a bit annoyed. The old hotplug wrapper has apparently
gone away. Why? I am curious. What if the receiver moves to some other
device file, say ttyUSB3? How do I detect and handle that other than
manually?
