I don't know what to suggest. Did you try "connect -r 7B"? In OVMF I'd probably add some DEBUG() calls to CoreConnectController() and to MNP's Supported() and Start() functions, to see where it goes wrong. I'd log the new child handle (the address) in my own Start(), and see if it turns up in CoreConnectController() somewhere, and if it's passed to MNP. Not sure if you can easily do that on your platform.
