Neos unable to "mix and match" Eye and Mouth Tracking Devices

Describe the bug?

I was helping a friend set up their Droolon Pi1 (Pimax) Eye Tracker + Vive Facial Tracker with no success. After some testing, I found that Neos does not like to "mix and match" devices. To recap:

The Pimax Eye Tracker would only function if and only if the Vive Facial Tracker was disabled.
Otherwise, the Facial Tracker would work but the Eye Tracker would not.

The two are mutually exclusive, and should not be.
