112	   At this writing, the OTG support in this driver is incomplete,
113	   omitting the mandatory HNP or SRP protocols.  However, some
114	   of the cable based role switching works.  (That is, grounding
115	   the ID pin switches the controller to host mode, while leaving
116	   it floating leaves it in peripheral mode.)
