Ah, this tripped me up before too. Don't use the second input of the instance node. This uses a points prim that's already been translated as USD. It will not inherit any attributes from USD points.

Attributes can be inherited from SOP points. To instance on SOP geometry, either put the instance points inside the instance node, or set the 'external SOP' path to point to the SOP geometry containing the instance points.
