USB1_OCn line status

Hi, I’m having trouble getting a set of devices all functioning together happily on a usb hub connected to the usb1 port on my BBB.

Does anyone know of tools to monitor the USB1_OCn line on the BBB? I’m looking for a way to check overcurrent that might already be baked into the systems we are using (angstrom, ubuntu builds), but if anyone knows otherwise I would appreciate more information.
