I've noticed USB issues on the mcbin too.
In my experience uaudio was the most likely thing to freeze: sometimes when playing audio the whole USB stack would hang, IIRC only unplugging and reconnecting the hub would let USB I/O continue.

Looks like the XHCI hardware might not be fully stable here?? but I do wonder if we could possibly lack some recovery mechanisms for this situation that other OSes have.
