Is Delphi jvclHidDevice ReportID the equivalent of USB endpoint?

I can make USB HID work in Delphi (2010) for simple stuff (one endpoint, ReportID = 0).

But now I need to send 96 words (192 bytes) of data every millisecond. I see how to do that in the slave (PICmicro) with three 64 byte endpoints. (Full speed Interrupt transfer is limited to 64 bytes per endpoint.) But I don't see either a more flexible USB/Delphi object or a way to specify endpoints in the JvclHIDDeviceController object.

Is ReportID telling me the received endpoint?

No. When used, it is the first of the 64 (maximum) data bytes.

Using WinUSB (or LibUSB-win32) and a bulk pipe sounds simpler to me than trying to create and access a composite device with 3 HID interfaces.
