Ok, now it is clearer than before. And If I use 3rd device for both playback
and capture I get this error:

Also below I have some questions...

How can I check this? I am really newbie for this things.
If your card doesn't support the needed parameters, you can use some

What are these plugins, I will install them, I dont have that .asoundrc
