Hi Paul,
First off, thanks a lot for your time! I really appreciate it.

Well, my device driver appears as a character device (IOKit USB driver
with an IOUserClient interface); it can be used to stream video in/out
of the system.

That could also be an option. But of course I prefer it to be possible
to directly load the video stream from the device driver into Final Cut
without additional applications.

I'll look into it, thanks a lot for your help and apt response!
