No Problem.  I thought uvdev had it's own hotplug pgm.  :-)

This is the z60_gpsd rule
# Prolific Technology, Inc. PL2303 Serial Port
SYSFS{idVendor}=="067b", SYSFS{idProduct}=="2303", SYMLINK="gps%n", 
RUN+="/lib/udev/gpsd.hotplug.wrapper"

and the related lsusb entry
Bus 006 Device 012: ID 067b:2303 Prolific Technology, Inc. PL2303 Serial 
Port

That is exactly what is in the file and the gpsd.hotplug.wrapper script 
does have the code doing what you describe, yet there is still no 
/dev/gps.  The code from both files is:

________
----Manual say /etc/defaults/gpsd should be
  START_DAEMON="true"
DAEMON_OPTS="-n"
DEVICES="/dev/gps"
___________

Weird huh.  Looks right except the ""$USBAUTO" = "true" ] || exit 0".
USBAUTO in *not* in the default/gpsd options mentioned in the manual 
instructions.

Thanks again for the reply Ross.
Maybe the fact that I have too many usb ports (4 on one card 5 on the 
other) on this box is causing this problem.

My UPS, ATT USB wireless modem, PicKit2 Programmer, external HD, and 
Kodak Camera Dock don't have a problem though.  Only thing that might 
mess up the works is that the ATT Modem uses ttyUSB0 through ttyUSB4 
when its connected to the net.
