ABSTRACT:
An apparatus, method, and system for coupling a host computer to a peripheral device over an extended distance. In one example, a first hub is provided for coupling with the host computer, the first hub configured as a compound device including a hub function and an embedded function, the first hub configured such that the embedded function is a virtual hub thereby providing an additional amount of time for signal transmissions by the first hub. A communications link is provided for coupling the first hub with the peripheral device, the characteristics of the communications link being based in part on the additional amount of time made available by the configuration of the first hub. In this manner, in one example, the length of the communications link may be extended beyond a standard USB cable length to consume the additional amount of time provided by the hub configuration, and transmissions may be made between the host computer and the peripheral device over the communications link in a manner that is within the USB timing specifications.
