SuperSpeed USB and Power Management

If you've ever asked yourself whether you understand power management issues for interfaces like USB, you would do well to read Mike Micheletti's article in EETimes on SuperSpeed USB's ability to deliver greater throughput while consuming less power. After an initial discussion of  ACPI-based power awareness and USB 2.0's Link Power Management (LPM) implementation, Mike explores the SuperSpeed power-management model and the power-state transitions required by the USB 3.0 specification. Mike is a regular contributor to the USB-IF Compliance Working Group, as is MCCI CEO Terry Moore.
