USB1_OCn pin - who is listening?

Hiya

The Beaglebone Black schematic has the over-current flag pin from the USB power controller for the USB host port connected to the AM3358’s T16 pin (say, GPIO1_26). Does anybody know why? Who is listening to that pin? I can’t find anything in the device manual about over-current, which suggests it needs to be handled in software. But what software? Any pointers, anyone?

Thanks in advance

It is there for someone to listen to.
