Back left port stopped detecting USB keyboard

AMD Framework 13 running Gentoo Linux.
QMK keyboard plugged into a thunderbolt hub.
dmesg shows the back left port detects the hub but not the keyboard.
The LED on the keyboard’s microcontroller lights up.
This setup used to work fine on the back left port.
Currently using the front right port instead.
Keyboard plugged in directly without hub also works in other ports, but not the back left.

The Linux tag isn’t showing up as an option for me on this thread.

Maybe try a cold boot? Power down, unplug from power, wait two minutes, plug back in, boot up, cross fingers…

Other things to try would be resetting the bios to defaults and resetting the mainboard. Best of luck, I hope that you get it working again.

It is working after a reboot!
