摘要：
Several embodiments including methods, systems, and physical computer-readable storage media are configured to multiplex a single end-point memory (EPM) structure between a HS USB interface and a SS USB interface, which includes determining whether the SS USB interface is enabled, if the SS USB interface is enabled, detecting the SS USB interface, selecting the HS USB interface, if the SS USB interface is enabled, but not detected, and multiplexing between a functionality of a HS USB device interface and a functionality of a HS USB host interface, if the SS USB interface is not enabled.
