0x09 is UAC2's EXTENSION_UNIT, which should not be a reason for failing. Please try the patch below.

Here is what I am getting after having changed the line in mixer.c:

Grant,
You had mentioned something about the end point for the mixer. I have found this information from the trace I had performed:
_From a dispatch urb_function_get_descriptor_from_device message under the fid_USBPORT_Endpoint_Descriptor:
fid_bLength 7 fid_bDescriptortype 5 fid_bEndpointAddress 0 fid_bmAttributes 0 fid_wMaxPacketSize 64 fid_bInterval 0
Is this what you were asking about, and does it help us?
thanks, David
