Claim:
1. A transmittal system, comprising: an extension device comprising a first connection port and a second connection port coupled to a peripheral device; a connection device comprising a third connection port and a fourth connection port, wherein the third connection port is coupled to the first connection port, and the fourth connection port is coupled to an electronic device; and an impedance device connecting at least one of the first, the third and the fourth connection ports to ground, wherein the peripheral device is capable of controlling the electronic device, wherein the extension device transmits signals between the peripheral device and the electronic device such that the peripheral device is capable of controlling the computing function of the electronic device, wherein each of the first connection port, the third connection port and the fourth connection port comprises a USB connector port with a corresponding identification (ID) pin, wherein the extension device is configured to serve as a hub to transmit data from the electronic device to the peripheral device and transmit data from the peripheral device to the electronic device, and wherein the impedance device comprises an internal resistor that connects the ID pin of the first connection port to the ground within the extension device for identifying that the electronic device is capable of being charged.
