Comment 33 for bug 1922336

I should add that on 5.12 there is no USB reset loop observed in my original post; USB devices attached to the dock just don't work at all when re-plugging in the dock, even sporadically. After re-plugging in the dock, the built-in laptop keyboard works, but calling anything that relies on sudo/root, even just "sudo dmesg" or "reboot" hangs indefinitely. The terminal keeps blinking, so it's not a complete hard freeze. Removing the dock again does not make it recover. Hard-reset is the only thing that is left at that point to get the system operational again.
