Abstract
A connection device including a first connection port, a second connection port, a third connection port and a chip is provided. When a host device is coupled to the first connection port and an electronic device is coupled to the second connection port, the connection device sets the level of an identification pin of the second connection port to a high level such that the electronic device operates in a device mode. In the device mode, the host device provides power to the electronic device. When the electronic device is coupled to the second connection port and a peripheral device is coupled to the third connection port, the connection device sets the level of the identification pin to a low level such that the electronic device operates in a host mode. In the host mode, the electronic device provides power to the peripheral device.
