It's not clear from reading your posts (unless it requires some correlation, on my part, of your observations) whether you have had storms on USB2 ports on several machines, or only on ones that appear to work intermittently. If the former, have they always involved the KVM? Do you configure the mouse at all, bearing in mind that unplugging and replugging it may lose that configuration. (I don't know how KVMs fit into this model.) Always bearing in mind that reporting against Debian 9 might only result in a stifled yawn. Cheers, David.
