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)?
