ADL USB detection?

Hi,
I use Q2686 module. How can I detect USB cable is pluged-in out disconneted ? I.e. is there feature as SoftConnect
and ho wcan I access it with ADL ?
There are ADL_FCM_EVENT_FLOW_OPENNED and ADL_FCM_EVENT_FLOW_CLOSED but they have no relation with cable plug -in/out…

Thanks.
