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
