Thanks for the help so far, Mikkel!
when I launch gpsd using:
gpsd -f /dev/ttyUSB0 -n -N
Dumb question - are you starting it as root? It needs to be run as
root to open the socket, and also to access /dev/ttyUSB0. It also
has to be started after plugging in the GPS.
In any case, if you are going to keep in it the foreground, you will
probably want to add D2 to your options.
gpsd -f /dev/ttyUSB0 -n -N -D2
You could make it a daemon by starting it with:
gpsd -f /dev/ttyUSB0
This is the way I would start it before I set up auto-handling of
hotplugged GPS devices.
and then try to launch xgps in another terminal window with:
xgps localhost:2947
You should be able to just run xgps.
the xgps application shows a status of 'UNKNOWN' and a GPS Type of
'unknown'. The other fields display 'n/a' and the status bar says 'no
data arriving'.
I would expect the type to say generic, or something like that.
At this point it is not working, but it may be the case that I have the
wrong command-line options...
Thanks again for the assistance...

You should also check to make sure you only have one copy of gpsd
running. I have to checked to see if the latest gpsd RPM starts gpsd
automatically. You should also check /var/log/messages to see if
there were problems. You should also expect a bit of delay between
plugging in the GPS and getting good data. How long the delay is
seems to be affected by the signal quality - it takes longer indoors
the outside, and starting in a car depends on the placement of the
GPS device or antenna.
If this does not do the trick, then I guess you will have to build
the module. If you have to do that, you may want to consider
building a kernel customized for your machine at the same time.

Hello-
yep, am running gpsd as root; only have one instance of the gpsd
program on my system, and only one instance running at a time. I have
left the antenna on for a bit with no change in the level of success;
even going outside did not improve my chances.
Not sure I've stated this, but running Fedora 7 64 bit on an AMD
processor HP laptop:

looked in /var/log/messages, go these entries after plugging in the
antenna:

checked for already-running gpsd and found none, so launched gpad and
after a second, xgps (as a non-root user) like this:

A couple of things jump out at me:

and, after xgps is launched, the entry:
gpsd: User requires 2, channel type is -1
The antenna continuously blinks red; I think the instructions say that
the led should go to yellow or green based on the strength of the
signal. Just a red blink here. I am going to try it with 'another
operating system' using the app that came with the antenna. Temp
test; would really like to get it working on my preferred OS.
Question: at one point I 'blacklisted' a few drivers on my system to
get the wireless net to work; would I need / be able to do that in
this case?
Still searching for more clues, but that is about all I have so far.
Help is always appreciated.
Paul
Well, it works on WindowsXP (a VMWare image on the same laptop) with the
DeLORME Street Atlas 2008 application; the led on the unit flashes
green and it sees 7 satellites. It is curious that the device is 'seen'
on plug in as an EarthMate LT-20, but gpsd tries to load a garmin device...
