Public bug reported:
I have a long askubuntu thread here:
https://askubuntu.com/questions/1521367/i-think-my-problem-is-
thunderbolt
Basically, I am only able to get my Anker 556 USB4 hub to work in the following
conditions:
- linux-image-6.5.0-1020-oem
- USB4 hub is plugged in before cold boot
Any time I hotplug the hub, it fails to get loaded. udev shows it
getting added and removed. syslog shows it getting loaded and
recognized, but then removed. tbtools and boltctl don't recognize it
unless the system was booted with the hub plugged in.
I'm not sure where else to go from here :(
