This register is only reset by a power-on reset (PCIRST#). It is written during system initialization to configure the Root Hub.
These bit should not be written during normal operation.

These bit should not be written during normal operation.
This register is reset by the UsbReset state.
Description
NumberDownstreamPorts (Read Only). USB supports three downstream ports.
PortPowerControlMask. Global-power switching. This field is only valid if NoPowerSwitching is cleared and Power-
SwitchingMode is set (individual port switching). When set, the port only responds to individual port power switching com-
mands (Set/ClearPortPower). When cleared, the port only responds to global power switching commands (Set/
ClearGlobalPower).
0: Device not removable.
1: Global-power mask.
Port Bit relationship - Unimplemented ports are reserved, read/write 0.
0 = Reserved
1 = Port 1
2 = Port 2
...
15 = Port 15
DeviceRemoveable. USB ports default to removable devices.
0: Device not removable.
1: Device removable.
Port Bit relationship
0 = Reserved
1 = Port 1
2 = Port 2

15 = Port 15
Unimplemented ports are reserved, read/write 0.
ClearRemoteWakeupEnable (Write Only). Writing a 1 to this bit clears DeviceRemoteWakeupEnable. Writing a 0 has no
effect.
Reserved. Read/Write 0s.
OverCurrentIndicatorChange. This bit is set when OverCurrentIndicator changes. Writing a 1 clears this bit. Writing a 0
has no effect.
Read: LocalPowerStatusChange. Not supported. Always read 0.
Write: SetGlobalPower. Write a 1 issues a SetGlobalPower command to the ports. Writing a 0 has no effect.
Read: DeviceRemoteWakeupEnable. This bit enables ports' ConnectStatusChange as a remote wakeup event.
0: Disabled.
1: Enabled.
Write: SetRemoteWakeupEnable. Writing a 1 sets DeviceRemoteWakeupEnable. Writing a 0 has no effect.
Reserved. Read/Write 0s.
OverCurrentIndicator. This bit reflects the state of the OVRCUR pin. This field is only valid if NoOverCurrentProtection
and OverCurrentProtectionMode are cleared.
0: No over-current condition.
1: Over-current condition.
Read: LocalPowerStatus. Not Supported. Always read 0.
Write: ClearGlobalPower. Writing a 1 issues a ClearGlobalPower command to the ports. Writing a 0 has no effect.
