I have a server system that I've had running for a couple of months - fresh install, Ubuntu 20.04 with all updates, and from day 1 it has had repeated messages, about every four seconds, that say, "usb usb2-port10: Cannot enable. Maybe the USB cable is bad?"
All USB ports that I know about are working fine, so this is either a port I don't know/care about, or a phantom message. I'm presuming it's the former.
What can I do to either identify the source of this "problem," or at least stop the proliferation in kern.log, syslog (and dmesg)? Maybe there's some process I need to stop? Or correct that process' configuration? It's truly a nuisance, when trying to find something useful in logs. (Yes, I know how to use grep... but still.....)
Here are some samples:
> sudo tail -50 /var/log/kern.log
