Or alternatively, if there are some devices with working Lynx Point xhci, we could disable enforced port routing on these models and use the default port configuration that machine comes up with (in my case there are no enabled xhci ports, PCI_XHCI_INTEL_USB3_PSSEN=0). I can base this argument only on some weird discussions where they mention Lynx Point having issues with port routing. https://lists.freebsd.org/pipermail/freebsd-usb/2013-October/012496.html
