Keyboard stops responding frequently. There is no output in dmesg when this happens. If I later unplug the keyboard I see a disconnection message in dmesg and I can reconnect it to the same port. Sometimes it works for a day after this, other times it works for <60s. Other devices disconnect too but the pattern is different. Much more likely to see the disconnect under heavy load, such as webcam/headset getting disconnected during a conference call.
