I have a Caldigit USB-C pro dock with a macbook pro m1 plugged into it, and I have been having random and inconsistent (sometimes once or twice a day, other times nothing for a couple of weeks) sudden devices disconnection. What's weird is that suddenly my keyboard, audio out and ethernet stops working, but my 4k monitor plugged in Display Port keeps working without a hitch.

I'm pretty sure it's an issue with the USB controller, and the article convinced me more, but I still have zero clue on how to begin troubleshooting an issue like that.

With every USB-C and/or TB hub/dock that I've ever used (including a Kensington SD5200T), I'd have periodic drop outs of my Plantronics wireless headset's connection. Directly connected to the laptop, never a problem.

Most recently, I've been using a Belkin 11-in-1 USB-C dock. I just checked, and I had it plugged into the USB 2.0 port on the dock before I moved it back to directly connected to my laptop. I've just plugged the headset back into one of the 3.0 ports, since this article says external 3.0 ports may not share like this article states.

I wonder if every other dock I've used, I've also been plugging into USB 2.0 ports that are sharing 3.0 ports...
