I think you have a mix of problems here. Let's fix up all of those error messages in the log first. Dan's fix has nothing to do with that at all, once the USB bus connection stuff is resolved, then it should be ok. As that xhci commit you point at is showing an issue, are you sure that you are properly building the right xhci driver into the system? Do you have a Renesas xhci controller? What is the output of 'lspci'? thanks, greg k-h
