Once a USB port has been attached, the CC logic also determines the orientation of the cable and configures the USB SS mux accordingly. The HD3SS2522 provides an VBUS_EN signal to control legacy power switch to provide 5 V to VBUS. The device also provides control signals needed to support 5 V VCONN sourcing for ecosystems implementing USB Type-C.
