I tryed with cheap USB cards and works. But what about for example Sound Blaster SB0490?

Does it support the USB audio class specification? If yes, then yes. The driver is for a specific USB audio standard. If the USB audio device supports that then the driver will work.

The best info one can get to recognize it seems to be: "plug and play".
