Bernd, thanks for the quick fix. Unfortunately I may have missed something earlier from not knowing the system well (or perhaps it changed due to lucid updates since yesterday?).
If I add the rule to /etc/udev/rules.d/launchpad-bug-518213.rules then when I plug the device I can see two entries in /dev (ls /dev | grep gps) and even if I add both to the DEVICES line xgps doesn't get any data. Now that you have pointed me to udev I see these lines in /lib/udev/rules.d/40-gpsd.rules: # PS-360 OEM (Microsoft GPS sold with Street and Trips 2005) SYSFS{idVendor}=="067b", SYSFS{idProduct}=="aaa0", SYMLINK="gps%n", RUN+="/lib/udev/gpsd.hotplug.wrapper" The Pharos GPS-500 also came with a version of Streets & Trips but is a newer version of the hardware (I also have the older GPS-360 which doesn't even work on Vista with the current Microsoft drivers, or else the unit is bad now). I see the USB vendor/product is unchanged between the two units (I confirmed both have same IDs - bad Microsoft / Pharos!). BTW, both Microsoft devices have Pharos on the tag on the back. So I think the change should be a comment in 40-gpsd.rules rather than a new rule altogether. To verify I commented out the launchpad-bug-518213.rulesI had created and now I can see a single /dev/gps* device appear when the device is plugged and see the dev go away when it is unplugged. But I am back to what I think should be auto detection not working as follows: If I set the DEVICES line to the /dev/gps0, 1, 2, etc. - it moves around) via dpkg-reconfigure gpsd then xgps will pick up the signal right away. If I add several devices (e.g. "/dev/gps0 /dev/gps1 /dev/gps2" to DEVICES trying to cover all bases then xgps doesn't get the signal at all (same as if I leave DEVICES blank to auto detect). And I have never seen xgps get the signal when DEVICES is blank (which I understand from the comments should be auto detect which is on per the default package install). I'm very sorry if I missed the /dev/gps* device on plug before filing the bug, I had been looking for it (since this is what I would hard-wire on Januty) and didn't see it yesterday and was setting DEVICES to the tty device I could see show up after plugging the GPS instead. Either way it seems there should be some combination that allows xgps (and I guess gpsd) to start listening to any single device that gets plugged and runs the gpsd.hotplug.wrapper. I would be more than happy to try some other stuff evenings after work next week.
