Not sure why webcamd doesn't start but you could try starting it
manually:

	webcamd -d 1.3

 If that exits too I guess it doesn't know your webcam, you can try
building its port with the DEBUG knob set and then look at the
terminal output (again when starting it with -d 1.3 .)

 Oh and you could also test the latest webcamd update Hans posted:

 HTH, :)
