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."},"analysis":{"summary":null,"layman_explanation":null,"technical_analysis":null,"business_analysis":null,"faqs":null,"topics":[],"tech_cluster":null},"seo":{"title":"Universal serial bus smart hub","description":"A USB smart hub may provide enhanced battery charging, data storage security, vendor matching, device authentication, data capture/debug, and role switching.
