Hi Marcel, I had tried with device class to 0x200404 and it didn't make any difference. I use the "scotest.c" to simplify the debug. The actual application is much more complicated. But the issue is similar with test result of "scotest.c". I assume the "scotest.c" should give me some valid data, as I sent so many real data from one side. I can actually receive real data with some USB dongles. But I have problem CSR chipset USB dongles with relatively newer firmware. That is something real confused me.

There is no guarantee that it does the right job. Some devices might send silence if the Headset or Handsfree profile is not fully setup.
