Intel RealSense Library for Processing

I’ve been trying to get my RealSense working, but I have kept getting “Realsense: no device found!”
The version I’m trying to use is a RealSense VF0800 (I got it at a hackathon years ago), and I’m now concerned that it may not work with any current software.
I’m not trying to do anything fancy - I just want to use it as a greyscale depth camera in Processing, but I’m getting no results.
