I'm also affected by this bug. I just did a fresh install of Xubuntu 20.04.1 and see the issue.

In my case it's "usb usb2-port1: Cannot enable. Maybe the USB cable is bad?".

There are no USB devices connected at all, so I get the bug with only the motherboard root hub present. I can make the log messages to syslog stop by inserting a USB3 device in one of the ports connected to usb2 (a USB2 device connected to the same physical port on the PC gets connected to a different bus so that will not make the log messages stop).

Booting Matthew's test kernel (5.4.0-42.46+TEST1856608v20200805b1) makes the bug go away. Booting the regular kernel (in this case 5.4.0-58-generic) and the bug is back.

So please revert the git commit on 20.04 (Focal) also until a fix is found.

I'll be happy to provide further info if needed.
