NumberDownstreamPorts. These bits specify the number
of downstream ports supported by the Root Hub. It is
implementation-specific. The minimum number of ports is
1. The maximum number of ports supported by OpenHCI
is 15.
0x03 = 3 downstream ports.
PowerSwitchingMode. This bit is used to specify how the
power switching of the Root Hub ports is controlled. It is
implementation-specific. This field is only valid if the
NoPowerSwitching field is cleared.
0: All ports are powered at the same time.
1: Each port is powered individually.
This mode allows port power to be controlled by either the
global switch or per-port switching. If the
PortPowerControlMask bit is set, the port responds only to
port power commands (Set/ClearPortPower). If the port
mask is cleared, the port is controlled only by the global
power switch (Set/ClearGlobalPower).
