Though we do control the VBUSVLD pin on DWC3 in the driver for the "Intel USB mux" Hans is introducing, the framework for the USB role switches does not provide any support for it. The Intel USB mux driver simply enables VBUSVLD when device mode is selected, and disables it if host mode is selected, and when the selection is cleared (disconnection).
