By typing this command I receive this message: "closed".
I generated a cosine wave on PD, and it works, but with a lot of noise.

Can you tell me why I get this "closed" message? And why there is so much noise on PD output?

I don't know this program, but please check the output of

  cat /proc/asound/USB/pcm0p/sub0/hw_params

after you started audio streaming with Mataa. This will show which
parameters the software configured the sound card to. You can also try
if PureData (pd) produces any output for example.
