This bit is set when the PES bit is cleared due to a
hardware event. This bit is not set by the change of writing

effect.

1: PortEnableStatus changed
Connect Status Change
This bit is set whenever the connection or disconnection
event occurs. Writing a 1 clears this bit. Writing a 0 has no
effect. If the CCS bit is cleared when SetPortReset,
SetPortEnable, or SetPortSuspend is written to, writing
when the power supply of the port is disconnected does
not occur, so this bit is set to enforce the driver to re-
evaluate the connection status.
