The HcRhDescriptorB register is the second of two registers describing the characteristics
of the root hub. These fields are written during initialization to correspond to the system
implementation.

Description
PowerSwitchingMode: This bit is used to specify how the power switching
of 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
ports supported by the root hub. The ISP1362 supports two ports and
therefore, the value is 2.
