PD crashes when [gemwin] is toggled to render when a natively supported Fire-I 785C camera is plugged in to the firewire port. It doesn't crash if the camera is not plugged in. What could possibly be causing this?

MAC OS 10.9.5
PD 0.43.4

**UPDATE: Just tested the camera in MAX/MSP with Jitter and works perfectly... But want it to work in PD!!
