Abstract:
1. A communication interface hub comprising: a plurality of ports, wherein one of the ports is an upstream port operative to be in at least one of direct and indirect communication with a host and wherein at least one other of the ports is a downstream port operative to be in at least one of direct and indirect communication with at least one device; at least one hub core coupled to the ports and implementing at least one physical hub; and at least one virtual hub core coupled to the ports and implementing at least one virtual hub, the at least one virtual hub core comprising a hub connect emulator coupled to the at least one hub core implementing the at least one physical hub to indicate coupling of the at least one virtual hub to the host, a sequence function block coupled to the hub connect emulator to control the hub control emulator to signal coupling of the at least one virtual hub to the at least one hub core implementing the at least one physical hub, and a virtual hub controller coupled to the at least one hub core implementing the at least one physical hub to manage traffic between the host and the at least one virtual hub, the at least one virtual hub being detectable as at least one physical hub by the host to cause the host to allocate an additional time delay in waiting for responses to signals output by the host.
