Notes 1.
When any device is not connected to all the ports of HC, the power consumption for HC does not depend
on the number of active ports.
2.
The number of active ports is set by the value of Port No Field in PCI configuration space EXT register.
3.
This is the case when PCI bus state is B0.
4.
This is the case when PCI bus state is B3.
Remark
These are estimated value on Windows XP environment.
