    OK to leave 3.0 RX/TX blocks unpowered if only using USB 2.0?

      Does anyone know if it is OK to leave the USB 3.0 1.2V supply pins (and associated logic powered by those pins) unconnected if the FX3 is to be used only for USB 1.1/2.0 communication? I didn't see anything in the datasheet or schematic design checklist (AN70707).
