+//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: Over-current Protection 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 hubs that do not
+//implement over-current protection.
+//
+//D6...D5: TT Think TIme
+//00:  TT requires at most 8 FS bit times of inter
+//transaction gap on a full-/low-speed
+//downstream bus.
+//01:  TT requires at most 16 FS bit times.
+//10:  TT requires at most 24 FS bit times.
+//11:  TT requires at most 32 FS bit times.
+//D7: Port Indicators Supported
+//0:  Port Indicators are not supported on its
+//downstream facing ports and the
+//PORT_INDICATOR request has no effect.
+//1:  Port Indicators are supported on its
+//downstream facing ports and the
+//PORT_INDICATOR request controls the
+//indicators. See Section 11.5.3.
+//D15...D8: Reserved
