Abstract
An apparatus and method for coupling a host computer to one or more peripherals or for coupling peripherals to one another. In one example, the apparatus includes a hub having an upstream port for coupling with the host computer and one or more downstream ports for coupling with the one or more peripherals; and a local host dynamically coupled with the upstream port. In one example, when the host computer is not coupled with the upstream port, the local host communicates with the peripherals; and when the host computer is coupled with the upstream port, the local host disconnects from the upstream port so that the host computer communicates with the peripherals through the hub. In this manner, the apparatus may be used to couple peripherals to a host computer, or when a host computer is not present, the data from the peripherals may be communicated through the local host. Other embodiments are also disclosed.
