Let me try this again.

gpsd is running
The "roadnav" application finds the GPS and reports 8 Sat's found and my
Latitude and Longitude.  The port it reports the GPS using is /dev/ttyUSB7.

If I modify /etc/default/gpsd like so
DEVICES="/dev/ttyUSB7"
gpsdrive does see the gps as well.

With gpsdrive running if I do "sudo telnet localhost 2947"
it displays "Escape character is '^['" and then times out.

Gpsdrive continues to run and the map downloaded for my location works.

So it seems that the default parameters for gpsd, DEVICES=/dev/ttyUSB?, 
have to be set for gpsdrive to work.  I tried setting 
DEVICES=ttyUSB[0-7], and DEVICES="/dev/ttyUSB0, /dev/ttyUSB7" but that 
did not work.
