(read)PortOverCurrentIndicator
This bit is only valid when the Root Hub is configured in such a way
that overcurrent conditions are reported on a per-port basis. If the
per-port overcurrent reporting is not supported, this bit is cleared to 0.
If cleared, all power operations are normal for this port. If set, an
overcurrent condition exists on this port. This bit always reflects the
overcurrent input signal.
0: No overcurrent condition
1: An overcurrent condition detected
(write)ClearSuspendStatus
HCD writes a 1 to initiate a resume. Writing a 0 has no effect. A resume
is initiated only if PortSuspendStatus is set.
(read)PortSuspendStatus
This bit indicates that the port is suspended or in the resume
sequence. It is set by a SetSuspendState write and cleared when
PortSuspendStatusChange is set at the end of the resume interval.
This bit is cleared when CurrentConnectStatus is set. This bit is also
cleared when PortResetStatusChange is set at the end of the port
reset or when the HC is placed in the UsbResume state.
0: Port is not suspended
1: Port is suspended
(write)SetPortSuspend
HCD sets the PortSuspendStatus bit by writing a 1 to this bit. Writing a
0 has no effect. If CurrentConnectStatus is cleared, this write does not
set PortSuspendStatus; instead it sets ConnectStatusChange. This
informs the driver that it attempted to suspend a disconnected port.
