[ gpsdrive ] GPSDRIVE can't communicate with my globalsat BU-353

[Hervé Gilibert]

My config:
Dell inspiron mini 9, Ubuntu 8.04.
USB GPS Globalsat BU-353
Gpsdrive 2.10 pre 4-1 and GPSD 2.36-2 installed from universe repository
using synaptic.

GPSdrive says "No GPS used"
When I telnet localhost 2947 I get:
$ sudo telnet localhost 2947
Trying 127.0.0.1...
telnet: Unable to connect to remote host: Connection refused
GPSDRIVE is launched using: gpsdrive -S -q -M pda -g 1024x600
GPSD is installed but not running:
gilibert at gilibert:~$ ps -edf | grep gpsd
gilibert  6652     1  9 00:01 ?        00:02:56 gpsdrive -S -q -M pda -g
1024x600
I thought GPSD was launched by gpsdrive ?
Thanks in advance for any clue for newby.
