This happened to me recently - on a Mac. If you’re on a Mac, please reboot and immediately after the bong, hold down command-option-P-R (you’ll need two hand unless you’re build radically different than most humans). There will be a delay and another bong. Release. The machine will not finish rebooting.
Did that clear the issue?
When this happened to me, the USB “gummed up”. A reboot didn’t clear it but the super reset did. Apparently there are parameters that get stored that can cause problems. I’m not 100% sure yet but the issue may occur more easily when USB 2 and 3 designed are mixed.
