After a few frames of black, a very green live picture
appears until about frame 50 when the picture goes
black - hitting q at this point then exits.

As requested in the README,  I've done
$echo 0x3f > /sys/module/gspca_main/parameters/debug
and issued the command
$./spcaview -d /dev/video1 -t
and attached the resulting section of /var/log/syslog.

I've not tried to use luvcview because this logitech
webcam is not a uvc device, as far as I know.
