[wdmaudiodev] Question on using SubmitIsoOutUrb

Hi,

I've read about using the SubmitIsoOutUrb method to submit urb directly to
the bus driver, and tried to query for the interface
USB_BUS_INTERFACE_USBDI_V0. But the SubmitIsoOutUrb member that I got from
the interface queried is always NULL. Does anyone know if this is actually
supported in XP/Vista, and if so, how to correctly query for this method to
use? Thanks
