22. HcRhPortStatus Register
NumberDownstreamPorts of the HcRhDescriptorA register represents the number of
HcRhPortStatus registers that are implemented in hardware. The lower word is used to
reflect the port status, whereas the upper word reflects the status change bits. Some status
bits are implemented with special write behavior (see below). If a transaction (token
through handshake) is in progress when a write to change port status occurs, the resulting
port status change must be postponed until the transaction completes. Reserved bits
should always be written 0.
The HcRhPortStatus register is used to control and report port events on a per-port basis.

This bit is set at the end of the 10-ms port reset signal. HCD writes a 1
to clear this bit. Writing a 0 has no effect.
0: Port reset is not complete
1: Port reset is complete
This bit is valid only if overcurrent conditions are reported on a per-port
basis. This bit is set when Root Hub changes the
PortOverCurrentIndicator bit. HCD writes a 1 to clear this bit. Writing a
0 has no effect.
0: No change in PortOverCurrentIndicator
1: PortOverCurrentIndicator is changed
This bit is set when the full resume sequence is completed. This
sequence includes the 20-s resume pulse, LS EOP, and 3-ms
resynchronization delay. HCD writes a 1 to clear this bit. Writing a 0
has no effect. This bit is also cleared when ResetStatusChange is set.
0: Resume is not completed
1: Resume is completed
