摘要： An apparatus includes a bi-phase mark coded (BMC) input port configured to receive BMC signals from a universal serial bus (USB) cable. The apparatus further includes a threshold adjustment circuit configured to generate a threshold, and a comparator configured to compare an input BMC signal from the BMC input port and the threshold and based on the comparison, generate an adjusted input BMC signal. The threshold adjustment circuit is further configured to adjust the threshold based upon the input BMC signal.

摘要： 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.

摘要： A system includes a power source, a universal serial bus (USB) type C port, and a multi-protocol adaptive circuit. The multi-protocol adaptive circuit may be configured to determine that a USB element has attached to the USB type C port, to determine whether to apply a USB type C charging protocol to the USB element or a legacy USB type A charging protocol to the USB element, and to provide power from the power source to the USB element.
