After insertion of the parallel port module you must get a console message
similar to this:

parport0: PC-style at 0x378, dma 3 [SPP,ECP,ECPEPP,ECPPS2]

The protocol ECP _must_ be in the list above. If it is not there stop
fiddling around with the camera-driver. It is not the cause and the camera
will _not_ work as long as you do not solve that problem first. I can think
of several possible causes: the bios/jumper-settings for the parport are
wrong as suggested by Bas; the linux parport driver might not support
ECP-mode on your parallel card chip (guess only possible for rather
exotic/old PCs); your parallel-port does not support ECP-mode (also only
for very old PCs).
