NodeInfo probably should return an error here...
If you so CAShow(auGraph) you should also see that the node is there, but hasnt' been opened yet (so there's no audio unit)
Thank you. Got the RemoteIO unit from the node and was able to set its input and output formats to kAudioFormatFlagsCanonical (I guess I was defaulting into 8.24, the audio unit canonical?).
In case anyone Googles their way here, what I needed to start my graph was
AUGraphNodeInfo - to get the unit from the node set properties on the unit AUGraphSetNodeInputCallback - on the node
Thanks again!
