Abstract
A computer system includes USB class protocol-aware modules for USB devices as part of a xHCI host controller. The protocol-aware modules serve as accelerators by implementing critical portions of the device class protocols, which includes fetching higher level protocol data directly from client buffers for transmission and delivering decoded data to client buffers on receipt; and emulating a register-based interface for the benefit of system software on the host computer.
