Are you talking about a microphone or headset that you plug into a USB port? If that is the case, they have to be treated like any other audio device using the Waveform interface.
See http://msdn.microsoft.com/en-us/library/windows/desktop/dd743832(v=vs.85).aspx[^]

That link is for the C++ interface, but it was just to get the ball rolling.

There are many resources on CodeProject for C# code to record sound. Here's a recent (April, 2014) article: "Play or Capture Audio Sound. Send and Receive as Multicast (RTP)" [^].

The BASS library (free for non-commercial use) is very powerful library for all types of sound manipulation, and playback [^]. There is a .NET API available with examples in C#: [^].

Is there a project with windows API? I must use windows API in some reasons.

The term "USB audio class" is the item which mislead you. It is not at all important from which type of external/internal connection the sound comes from. Also an external sound card connected via USB is simply: a sound card. So just look for any tutorial on audion recording in your preferred programming language - omit that "USB" because it is irrelevant.
