First, the OTG port has the "bvalid" interrupt enabled, not "linestate". Since only the linestate interrupt was handled, and not the bvalid interrupt, plugging in a cable to the OTG port caused an interrupt storm. Second, the return values from the individual port IRQ handlers need to be OR-ed together. Otherwise, the lack of an interrupt from the last port would cause the handler to erroneously return IRQ_NONE.
