USB3.1 Gen1 Type C interface 2. Two USB2.0 Type A interfaces via an on-board USB Hub. By default, the USB3.1 Gen1 Type C interface is supported on both of the EVMs. Enable the USB2.0 Type A interface by configuring the USB2.0_MUX_SEL mux. Additionally, set the Dual-Role Mode to Host since a Type-A interface is only associated with the Host Mode of operation.
