HcRhDescriptorB Register
The HcRhDescriptorB register is the second register of two describing the
characteristics of the Root Hub. These fields are written during initialization to
correspond with the system implementation. Reset values are
implementation-specific (IS).

affected by a global power control command when
PowerSwitchingMode is set. When set, the port’s power state 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 configured to global
switching mode (PowerSwitchingMode = 0), this field is not valid.
