condition) or by the host software. Note that the bit status does not change until the port state actually
changes. There may be a delay in disabling or enabling a port due to other host and bus events.
all changes to the port device connect status, even if system software has not cleared an existing connect

indicated by the High Speed Port bit in this register. A zero indicates that the device did not attach
successfully or was forcibly disconnected by the software writing a zero to USBCMD[RS] (run bit). It does
not state the device being disconnected or suspended.
