Hi,

I'm afraid I need my hand on your device to figure this out.

When the device init fails, it means that SET-ADDRESS fails, and without that 
we are lost.

You could try setting this variable in /boot/loader.conf

hw.usb.xhci.xhci_port_route="0xFFFFFFFF"
hw.usb.xhci.xhci_port_route="0x0"
hw.usb.xhci.xhci_port_route="0x1"
hw.usb.xhci.xhci_port_route="0x2"
hw.usb.xhci.xhci_port_route="0x4"
hw.usb.xhci.xhci_port_route="0x8"

And so on.
