Then it should be as I wrote earlier: a single hardcoded 1/0->0/0 route in the sensor, and .get_frame_desc() returns VC 0 and a suitable DT for that stream. When you say "implementing virtual channels as streams", what is the feature/requirement you are looking at? Do you have some specific need to use other VCs than 0? Tomi
