  • Load balancing in multi-port USB systems
    Patent number: 10976790
    Abstract: An apparatus includes a processor, USB connectors, and variable resistors or variable current sources. The processor is configured to read and load instructions causing the processor to dynamically adjust a current consumed by a given connector through adjustment of a related variable resistor or variable current source.
    Type: Grant

  • USB power port control
    Patent number: 9715271
    Abstract: A system, method and device for providing over-current protection to USB ports comprised in a USB hub, whereby a single switch is used to control the power supply to one or more groups of USB ports based on determinations whether the current drawn by a group of USB ports has exceeded a predefined current limit. Embodiments provide the cost savings associated with gang mode power port switching and the reduced stress on USB components and individualized protection of USB ports associated with individual mode power switching. Embodiments utilize a plurality of current measurement units to measure the current drawn by each group of USB ports supported by a switch and further utilize a power port control logic unit to control the switch based on whether the current measurements have exceeded a current limit.
