Thanks for the link!!

Well maybe it *should have*, but it didn't/doesn't.  I don't have 
/dev/gps.  So I changed /etc/default/gpsd to what the  8.04_manual has 
for that file. Unplugged the gps, stopped gpsd, restarted gpsd, plugged 
gps in.  Ran gpspipe -r which displays one line "GPSD, R=1", and still 
no /dev/gps and gpsdrive can't see the gps.

Debian Squeeze does not have a hotplug package.  It has been replaced 
with udev IIRC.  So it seems, to me anyway, that the
  /etc/udev/rules.d/z60_gpsd.rules file should be creating the /dev/gps
device.  There is no reference to it in that file though or any mention 
of /etc/default/gpsd.

What are other Debian Squeeze users seeing?

Switched the default/gpsd back to what I had and gpsdrive is working 
again and plotting the gps which is on /dev/ttyUSB7.

The 8.04 manual instructions dit not work for setting up the databases 
either.  Guess Ubuntu is a bit different the Debian Squeeze.

Thanks for your reply Ross.
