I'm having some issues with a BU0836X...

I bought a BU0836X a few months ago to replace the controller in a Saitek yoke. Everything was working great, but recently I noticed some issues.

I observed some noise in the elevator control (Y axis) around the center position. As I move the yoke, there's considerable "jumping" around, which smoothes out at the extremes of the axis.

This is visible under the Control Panel Game Controllers BU Test tab (the + cursor exhibits this behavior) but it is not apparent during calibration (displaying the raw data). That is, the raw data seems to increase smoothly regardless of axes positions, but after calibration it's "jumpy".

It seems odd that the values during calibration do not exhibit any noise (no "jumping" as I smoothly pull or push the yoke through the center) but do in the actual use/test area.

What can I do to debug this further? Is there some logging I can enable to see raw values read by Windows and the translated output? I'd like to determine whether's some Windows issue or a hardware problem I'm having.

Any one run into anything like this before?
