USB PCI Host Controller
No device connected
Port disabled.
If the port has power control, software cannot change the state of the port until it sets the
port power bits. Software must not attempt to change the state of the port until power is
stable on the port; maximum delay is 20 ms from the transition. For bit allocation, see
Table 106
.
[1]
The reserved bits should always be written with the reset value.
