ABSTRACT:
A concentrator connects multiple downstream devices to an upstream host using the same device address. The concentrator combines together configuration information obtained from the multiple downstream devices. The combined information appears to the host as coming from the same device. Multiple peripheral controllers may be configured to respond to different endpoints or alternate interfaces associated with the same device address. In one implementation, the downstream devices, the concentrator, and the upstream host all communicate using Universal Serial Bus (USB) connections.
