as a quick hack, use the following command just after you started
gpsd to force the parity to non on the serial line:
root at grml ~ # gpsd -n /dev/ttyUSB0
root at grml ~ # stty -F /dev/ttyUSB0 -parenb -parodd
When in debug-mode, gpsd then spits out the following lines:

Unfortunately, it does not show any information about time or position on
a connected cgps/xgps client.
