Currently UCSI framework doesn't update USB data role when partner type is reported as power cable or power cable with ufp connected. This results into no USB host mode functionality. This is valid usecase where user wants to use legacy type c power cable with type a female connector to attach different USB devices like mouse, thumb drive etc. Hence update USB data role as host when partner type is reported as power cable or power cable with ufp connected.
