Custom firmware and USB hubs? Valid threat. I would allow reputable vendors though. I help define the policies at my current workplace and we block anything that isn't an hid device or purely charging (headsets, phones are blocked from mounting storage) . Also no non-computing related accessories, so no usb flash drives, mug warmers, or deskfans-sorry.
