Got an external Logitech camera that we use for work. I tend to keep mine disconnected and just do any Teams/Zoom meetings with no video unless I'm presenting, and that's because the mouse tracking is severely delayed and impaired when the camera is connected via USB.
I have no idea why that is, but it's annoying as hell.
This could also go in the grumpy old man thread. I would like to know what's causing that and if there's a fix for it. I'm not the only one with that issue. Several of my coworkers tell me they have the same problem.
