HcRhStatus register (R/W: 14H/94H)
The HcRhStatus register is divided into two parts. The lower word of a DWord
represents the Hub Status

PortPowerControlMask:
Each bit indicates whether a port is
affected by a global power control command when
PowerSwitchingMode is set. When set, the power state of the port
is only affected by per-port power control (Set/ClearPortPower).
When cleared, the port is controlled by the global power switch
(Set/ClearGlobalPower). If the device is con
fi
gured to global
switching mode (PowerSwitchingMode = 0), this
fi
eld is not valid.

DeviceRemovable:
Each bit is dedicated to a port of the Root
Hub. When cleared, the attached device is removable. When set,
the attached device is not removable.
