I got the disks to attach at USB3.0:

What I did:
a) Set hw.usb.xhci.xhci_port_route="0x3" in /boot/loader.conf
b) Fixed /sys/dev/usb/controller/xhci.c as follows:

     --- dev/usb/controller/xhci.c   (revision 268290)
     +++ dev/usb/controller/xhci.c   (working copy)
     @@ -567,7 +567,7 @@
             if (sc->sc_port_route != NULL) {
                     /* Route all ports to the XHCI by default */
                     sc->sc_port_route(sc->sc_bus.parent,
     -                   ~xhciroute, xhciroute);
     +                   xhciroute, ~xhciroute);
             }
             return (0);
      }

Previously when I set the port route mask to -1, the xhci init would 
fail.  It seems for my H81 board that only ports 1 and 2 are available 
for USB 3.0 [1] so only the value 0x03 for the port route would work for me.
