Abstract: A USB smart hub may provide enhanced battery charging, data storage security, vendor matching, device authentication, data capture/debug, and role switching. The smart hub may include an upstream port, a plurality of downstream ports, a processor, and a memory coupled to the processor for storing USB host stack code and configuration parameters. The smart hub may include a USB hub core having a core to implement a standard USB hub interface. The smart hub may include a plurality of 2:1 multiplexors coupled between the downstream ports, the core downstream ports, and the processor. The processor may control the 2:1 multiplexors. The processor may be configured to detect when a USB device is coupled to a downstream port and to run the USB host stack code and to enumerate the USB device. The processor may provide enhanced features based on the configuration parameters.

Abstract: A multi-host endpoint reflector enables a method of communication between multiple USB hosts through the USB devices connected to them, where data from one USB host is routed across the USB devices between endpoints of complimentary directions to one or more additional USB hosts. The multi-host endpoint reflector may be integrated with a USB hub controller to form a USB compound device to create a multi-host endpoint reflector hub. A USB multi-host endpoint reflector hub enables a USB OTG B device to become a host upon request by providing a data bridge between the OTG B device after it has transitioned to a host role while any other OTG A device that already is a host is not required to change its host role to a slave role. Therefore a plurality of OTG host devices may co-exist on the same interconnection system hub and communicate there between.
