Abstract
An electronic device that is able to operate by receiving a power supply from a host device through a Universal Serial Bus (USB). The electronic device acts as a first sink device and is connected to a second sink device that is able to operate by receiving a power supply from the host device through the USB and the connection to the first sink device. Each of the first sink device and the second sink device is provided with a CC terminal that obtains power supplying capability information from the host device, a pull-up or pull-down resistor connected to the CC terminal, and a GND terminal that grounds a circuit of the CC terminal and the pull-up or pull-down resistor. The electronic device changes a state of grounding of the pull-up or pull-down resistor to the GND terminal, in one of the first sink device and the second sink device.
