Logitech Saitek throttle quadrant ... Jitter! Help?

All good suggestions, thanks everyone.
Still I find it odd that this is on a brand new unit, and the jitter is much less in other sims and almost 0 outside of any application at all.
I’m pretty sure it’s my system and something to do with the USB ports… or some weird combo…
It’s bad enough that the throttle in the model actually jumps back and forth, at first I was pretending it was motor vibration. :wink: But it does it with the motor off of course.
