I'm trying to save a hermite curve to usd basis curve and use in Houdini but the saved curve seems incorrect in usdview [graphics.pixar.com] and unpackusd [www.sidefx.com].
It seems to be not supported judging from the source code.

https://github.com/PixarAnimationStudios/USD/blob/be1a80f8cb91133ac75e1fc2a2e1832cd10d91c8/pxr/usd/usdGeom/basisCurves.cpp#L201-L221 [github.com]

BasisCurves do not yet support hermite or power bases.

The step size for hermite curve should be 2, I think.
