Thanks! Sorry for the late reply. I've done a little testing on my end and have noticed something that might be of interest. I experience the issue more on what I would consider "slow" devices. I typically use a raspberry pi, PI 3 MODEL B, for controlling my scope and gear. The pi, as we all know, has rather slow USB ports/IO. The issue is very reproducible on the pi.
