the Root Hub. Reset values are implementation-specific. The descriptor length (11),
descriptor type (TBD), and hub controller current (0) fields of the hub Class Descriptor are
emulated by HCD. All other fields are located in the HcRhDescriptorA and
HcRhDescriptorB registers.
The HcRhDescriptorA register is one of the two registers describing the characteristics of

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
This byte specifies the duration HCD has to wait before it accesses a
powered-on port of the Root Hub. It is implementation-specific. The
unit of time is 2 ms. The duration is calculated as POTPGT
This bit describes how the overcurrent status for the Root Hub ports is
reported. When this bit is cleared, the OverCurrentProtectionMode
field specifies global or per-port reporting.
0: Overcurrent status is reported collectively for all downstream ports
1: Overcurrent protection not supported
This bit describes how the overcurrent status for the Root Hub ports is
reported. At reset, this fields should reflect the same mode as that of
PowerSwitchingMode. This field is valid only if the
NoOverCurrentProtection field is cleared.
0: Overcurrent status is reported collectively for all downstream ports
1: Overcurrent status is reported on a per-port basis
This bit specifies that the Root Hub is not a compound device. The
Root Hub is not permitted to be a compound device. This field should
always read/write = 0.
These bits are used to specify whether power switching is supported
or whether ports are always powered. It is implementation-specific.
When this bit is cleared, the PowerSwitchingMode specifies global or
per-port switching.
0: Ports are power switched
1: Ports are always powered on when the HC is powered on
These bits specify the number of downstream ports supported by the
Root Hub. It is implementation-specific. This module has one port, so
0x01 is read.
controlled by either the global switching 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,
then the port is controlled only by the global power switch
(Set/ClearGlobalPower).
