A wild guess:

Copy the USB-code from -current.

Add "#if 0" as shown sys/dev/usb/controller/xhci_pci.c

static int
xhci_pci_port_route(device_t self, uint32_t set, uint32_t clear)
{
#if 0
         uint32_t temp;

         temp = pci_read_config(self, PCI_XHCI_INTEL_USB3_PSSEN, 4) |
             pci_read_config(self, PCI_XHCI_INTEL_XUSB2PR, 4);

         temp |= set;
         temp &= ~clear;

         pci_write_config(self, PCI_XHCI_INTEL_USB3_PSSEN, temp, 4);
         pci_write_config(self, PCI_XHCI_INTEL_XUSB2PR, temp, 4);

         device_printf(self, "Port routing mask set to 0x%08x\n", temp);
#endif
         return (0);
}
