Abstract:
A communication interface hub includes multiple ports, where one of the ports is an upstream port operative to be in direct and/or indirect communication with a host and at least one other of the ports is a downstream port operative to be in direct and/or indirect communication with at least one device. At least one hub core is coupled to the ports and implements at least one physical hub, and at least one virtual hub core is coupled to the ports and implements at least one virtual hub. The virtual hub is 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.
