TrackIR causes aircraft roll?

[naloxone]

So I had been using TrackIR and Opentrack at different times for head tracking. In September, I had moved and packed up my computer. DCS was working fine with either head tracker.

 

Now this past week, I've set up my rig again and whenever I use head tracking, either opentrack or TrackIR, my aircraft rolls left. 

 

Turning off the head tracking software corrects the roll. The roll is not present in other simulators (MSFS, IL2, and Elite). Turning off the roll axis in the head tracking corrects the roll but obviously limits my range of motion.

 

I have clean installed all the tracking software as well as DCS. Wiped all binds and started from scratch. 

 

I'm stumped. Anyone have any ideas?
