Please use the public Linux USB mailing list to report xHCI issues. I've Cc'ed Mathias Nyman, who took over as xHCI maintainer two years ago. You can find the maintainers of your drivers in the MAINTAINERS file, which is in the Linux kernel source code and online: http://lxr.free-electrons.com/source/MAINTAINERS Good luck debugging this!
