LPC546xx: USB interrupt pipe polling notification

Is there a way to be notified when the host polls the USB interrupt IN pipe? I looked at the USB example projects and it seems that USB0_IRQHandler is not triggered when the device has nothing to report, i.e. responds to the interrupt poll with NAK. I would like my code to be notified when it receives the interrupt IN poll from the host.
