wHubCharacteristics:
  D1...D0: Logical Power Switching Mode
    00: Ganged power switching (all ports power at once)
    01: Individual port power switching
    1X: Reserved. Used only on 1.0 compliant hubs that implement no power switching

  D2: Identifies a Compound Device
    0: Hub is not part of a compound device.
    1: Hub is part of a compound device.

  D4...D3: Logical Power Switching Mode
    00: Global Over-current Protection. The hub reports over-current as a summation
        of all ports’ current draw, without a breakdown of individual port
        over-current status.
    01: Individual Port Over-current Protection. The hub reports over-current on a
        per-port basis. Each port has an over-current status.
    1X: No Over-current Protection. This option is  allowed only for bus-powered
