       Yes, the audio device is a UAC1 device, and it used
   set_sample_rate_v1 to set sample.

       So, I add a quirk to keep up the USB interface up even if the audio
   stream is closed.

   I received your previous mails including lsusb -v output.  But the
   post was filtered out by some reason?
   So the audio device looks like a UAC1 device.  And this one requires
   to keep up the USB interface up even if the audio stream is closed
   (not about the parameter changes)?
