ROM USB MIDI cant seem to get Interrupts to fire

I am trying to get a ROM USB MIDI device running on an LPC51U68 using MCUxpresso similar to the Microchip MIDI tone generator example . ( which runs out of the box )

I am to be able to initialize and register the Rom handlers without errors . Same descriptor which is working with Microchip example.

ret = USBD_API->hw->Init(&g_hUsb, &desc, &usb_param); = LPC_OK

ret = USBD_API->core->RegisterClassHandler(hUsb, ADC_ep0_hdlr, pAdcCtrl); = LPC_OK

ret = USBD_API->core->RegisterEpHandler(hUsb, pSubs->ep_index, ADC_iso_out_hdlr, pSubs); = LPC_OK

USBD_API->hw->Connect(g_hUsb, 1); is OK and my computer enumerates it fine.

But I cant seem to get any Interrupts to fire for the registered class ADC_ep0_hdlr or other EP handlers.

Any one have any ideas? Do they only fire if I receive something, so do I need to send something to my device or should the class handler fire all the time when the usb link is open?

Any way to debug this?

Got them to fire but WriteEP crashing. I guess I'll submit a ticket... seems pointless talking to myself.
