I can confirm this issue in 20.04 linux-image-5.4.0-42. This message only appear for my usb3.1 gen1 type-c hub when it is connected on boot. If I re-plug the hub after boot, the message stops. It doesn't appear for another connected usb3 type-a hub.
In /var/log/syslog, it prints every 4 seconds: Aug 3 01:57:37 fox kernel: [ 6020.600964] usb usb2-port2: Cannot enable. Maybe the USB cable is bad?
