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.

Description
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 valid only if the NoPowerSwitching (NPS) field is
cleared.
0 — all ports are powered at the same time
1 — each port is individually powered. This mode allows port power to
be controlled by either the global switch or per-port switching. If the
PortPowerControlMask (PPCM) bit is set, the port responds to only
port power commands (Set/ClearPortPower). If the port mask is
cleared, then the port is controlled only by the global power switch
(Set/ClearGlobalPower).
reserved
downstream ports supported by the Root Hub. It is implementation
specific. The maximum number of ports supported is 2.
