The problem I have with changes like this is that outside of your
stress test situation these messages are extremely useful but will
now be hidden making diagnosis of problems more difficult.

Perhaps you can check the error code or some piece of USB device
state to see if there was a disconnect, and elide the log message
in that case specifically.

Thanks.
