Methods, systems, and physical computer-readable media for multiplexing a single end-point memory structure between USB interfaces

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.

1. A method of multiplexing a single end-point storage structure between a High Speed (HS) USB device interface, a HS USB host interface, a Super Speed (SS) USB device interface, and a SS USB host interface, the method comprising:
determining whether a SS USB interface is enabled; detecting the SS USB device interface or the SS USB host interface, if the SS USB interface is enabled; selecting a HS USB interface, if the SS USB interface is enabled, but not detected; and multiplexing between a functionality of the HS USB device interface and a functionality of the HS USB host interface, if the SS USB interface is not enabled.
