Note: The power consumption is measured when the bus is in IDLE state – there is no activities other

than the Start-Of-Frame (SOF) and INTERRUPT-IN packets for the hub itself on the bus. The peak

power consumption varies depending upon the system configuration, type of operations, and over-all

bus utilization.
