Abstract: A dongle coupled between a power supplying device for supplying power and a power receiving device for receiving power includes a downstream facing port (DFP), an upstream facing port (UFP) and a controller. The controller is arranged to control deliveries of the power and messages between the power supplying device and the power receiving device. In response to a first power request message received from the power receiving device, the controller is arranged to determine whether a power type request by the power receiving device is Programmable Power Supply (PPS) according to the first power request message. When determining that the power type request by the power receiving device is PPS, the controller is arranged to start first waiting timer, and when the first waiting timer expires, the controller is arranged to send a request accept message to the power receiving device through the UFP.

Abstract: This prevention provides a method for wirelessly controlling an electronic device with a quick response code. The method is performed in a calculating device with internet capability. The method comprises receiving a graphics information of the quick response code of the electronic device, decoding the quick response code, downloading a controlling and driving program of the corresponding electronic device for installation according to the decoded quick response code, configuring an internet protocol of the electronic device by the controlling and driving program, and controlling the electronic device by the controlling and driving program through the internet protocol wirelessly. Accordingly, the calculating device with internet capability can control the electronic device with a quick response code, such that the calculating device with internet capability can improve living facilities of the user.
