Linux uses a different device structure (Video4Linux) for video input 
than OS X, so [pdp_v4l] will never work.

In short, Linux users can access a USB camera with [pdp_v4l], but not a 
firewire one.
OS X users can access a firewire camera with [pdp_ieee1394], but not a 
USB one.

If you use GEM on OS X, you can access either. You might need the macam 
drivers to use the USB camera:
