The active mode is determined primarily by checking the speed of the enumerated USB device. When USB Power Delivery is supported, the active USB mode should be always the mode that was used with the Enter_USB Message, regardless of the result of the USB enumeration. The port drivers can separately assign the mode with a dedicated API. If USB Power Delivery Identity is supplied for the partner device, the supported modes are extracted from it.

However, after UCSI v2.0 it is possible to check separately is USB4 the active mode. So with USB2 and USB3 the mode is always determined from the result of the USB enumeration, and when USB4 USB Mode is active, UCSI driver can assign the mode directly.
