xhci_hcd 286720 1 xhci_pci
renesas should provide version firmware that can be loaded under linux , it concerns xhci & USB3
( USB3 has been review for securities about stack USB )
this is a warning version renesas is not loaded , and we have still a minima for USB3 ( 5Gb )
There have been several patches to it. The most recent patch is in linux-next. It basically turns off some edits which were interfering with the driver loading.
Any chance of getting a 5.8.3 build with this patch>
