I've attached an egpu over thunderbolt to my Galago Pro and started to see these messages. The connected bluetooth devices started to freeze for 1-2 sec idle time from time to time, then these messages appear in the syslog. The strange thing, that the USB devices plugged into the egpu case are working flawlessly (one webcam and a mouse). I've tested the 20.04 dev iso as well. it has the same issue.
It seems if I have a continuous use of bluetooth (like playing audio with it) this issue does not happen. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1850172 Title: syslog flooded with these USB messages, but device doesn't exist To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux-signed-hwe/+bug/1850172/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
