It should also be noted that the identity of each device is different, so that the type of device may be determined by the identity of the device, and the type may include USB2.0 and USB3.0. In a specific determination process, for example, when the identifier of the device of USB2.0 stored in advance contains the acquired identifier of the device, the type of the device is determined to be USB2.0.
Meanwhile, the judgment result may be finally displayed by printing. In addition, after the standard of USB4.0 is executed, the compatibility determination may also be performed with reference to the present application.
