ABSTRACT:
A USB multi-function connecting device includes a peripheral device connector and a pair of data upstream port and data downstream port, wherein the data upstream port is to connect the USB (Universal Serious Bus) port of a computer for receiving the peripheral device control command and data transmission from the computer. The peripheral device connector is adapted to be connected to a peripheral device and to freely define the peripheral device definition that represents the peripheral device connected thereto by the control circuit in response to the peripheral device control command from the computer so as to control the peripheral device connected thereto. The data downstream port provides a connection to an identical device in a next level or a further next level so as to interconnect the USB multi-function connecting devices to provide a multiplicity of statuses for operating different peripheral devices at the same time and thus providing a seriously-connected, multi-device, multi-function and multi-purpose USB connecting device.
