are you related to Phillippe Michaud by any chance? Army officer stationed in Germany in 1979
Our team is experiencing EXACTLY the same issue (same repro steps, same symptoms) as you describe here, with both our robots (both are Rev Control Hub that we bought in 2023).
We observed the exact same thing on the two Control Hubs we have! Maybe the weather got colder and dryer and it caused these ESD events to happen a lot more often. We never got issues like this one during the summer.
