USB Bus Topology

This section briefly describes the topology and communication model for the USB architecture.

The USB architecture has a well defined physical and logical bus topology, which is fully described in the Universal Serial Bus Specification. The physical topology defines how USB devices are connected together. The logical topology defines how the various components that make up the physical topology are viewed by the host software.
