In the case where USB power is first applied and a 20V contract established, the STUSB4500 would enable the power path to Vsnk as per usual. Then assume a 20.9V (for example) secondary power source is applied to the Vsnk output (say from a wall adapt...
Also, will the VBUS_EN_SNK pin get asserted (pulled low) in this case, allowing the power path to enable 5V from the USB 2.0 cable to power the device?

Are these endpoint values OK:
UVC_IN_EP 0x81
UVC_CMD_EP 0x82
CDC_IN_EP 0x83
CDC_OUT_EP 0x03
CDC_CMD_EP 0x84
