Abstract
An intermediate electronic device, arranged to be coupled to a host system and an electronic device. The intermediate electronic device includes: a controller, enabled by an enable signal to process the data transmission between the host system and the electronic device; and a power transmission unit disposed between the host system and the electronic device. The power transmission units detect whether the power transmission unit is coupled to the host system or an external power source. When the power transmission unit detects that the power transmission unit is coupled to the host system, but not coupled to the external power source, the power transmission unit informs the host system to raise the voltage output to the intermediate electronic device to supply power to the electronic device, and outputs the enable signal.
