Hi,

In sys/dev/usb/controller/xhci.c

Try to increase the usb_pause_mtx() from hz/1000 to hz/100.

If that doesn't work try to continue, even if the HC is not clearing the HCRST 
bit. Also print "temp" at the end of the loop.

        /* Reset controller */
        XWRITE4(sc, oper, XHCI_USBCMD, XHCI_CMD_HCRST);

        for (i = 0; i != 100; i++) {
                usb_pause_mtx(NULL, hz / 1000);
                temp = XREAD4(sc, oper, XHCI_USBCMD) &
                    (XHCI_CMD_HCRST | XHCI_STS_CNR);
                if (!temp)
                        break;
        }

        if (temp) {
                device_printf(sc->sc_bus.parent, "Controller "
                    "reset timeout.\n");
                return (USB_ERR_IOERROR);
        }
