(READ) CurrentConnectStatus: This bit reflects the current
state of the downstream port.
0 = no device connected
1 = device connected
(WRITE) ClearPortEnable: The HCD writes a “1” to this bit
to clear the PortEnableStatus bit. Writing a “0” has no
effect. The CurrentConnectStatus is not affected by any
write.
