Detailed Description

template<typename audio_stream_t, typename midi_stream_t, typename desc_t>
class dxd::portcls::device< audio_stream_t, midi_stream_t, desc_t >

adapter device streaming a lower device stack

Obtains the pin descriptions from the lower device (wdm_bus) and generates the miniports with appropriate cable, endpoint and queue size.
