Looking back through my reboots in journalctl
, it looks like I’ve been getting this notification rather consistently near/at the top of my logs…
$ journalctl -k --priority err

Dec 10 15:01:33 AM4-5600X-Linux kernel: ucsi_ccg 0-0008: failed to get FW build information
Doing a quick DDG, I see some references that made me think this might have something to do with USB… but I’m not sure.
If it is USB related, I know I’ve always had a question about what this odd/blank entry is in my USB list…

If I was to guess what this odd USB entry is, I’d say it was the USB-C port on my AMD 6800XT… because it is absent from the global lsusb list…

Yet does make it’s presence known in the lspci

Any assistance understanding what this message means and what my actions should be would be greatly appreciated. My guessing and DDG research isn’t getting me very far… and I have a suspicion that the GPU’s USB Controller
might be one of the many listed Linux Foundation X.0 root hub
entries… meaning I’m chasing red herrings.
