hid_param.HID_EpIn_Hdlr not called

I've implemented the core functions of the LPC11u24. Device enumerates correct, however transmitting reports is a problem.

As far as I understand the EP handler registered with "hid_param.HID_EpIn_Hdlr" should be triggered, each time the host

polls the device. This isn't the case now. If I call USBD_API->hw->WriteEP from within the main, the handler will be called, what I didn't expect.
So is the scenario:

host polls -> trigger EP handler -> write to endpoint


write to end point -> trigger EP handler

In case of the first, what goes wrong.
