Have you got an answer?
I would ask this, You said that the unit engages a button or buttons, could you be more specific?
Is it strictly the same button every time or is it multiple, and if multiple is it always the same ones?
Is it a selection point on a high hat switch?
I would go into windows controller game settings and just let it sit, does an input register, all items will blink when engaged, yes?
Does same issue occur with device drivers installed/uninstalled? only in game or all times?
Does disabling any game selection to said button end issue?
That's a HOSTAS, unplug the throttle unit from stick unit, same issue?
Basically see if you can discover which component is errant, isolate, then disable or fix. If you have no basic skills and knowledge in electronics, meter and soldering iron, you will prolly just disable and not use.
