I have two similar usb audio device.
When I read "AudioDevicePropertyDeviceName",
I get two same name.

How can I know, which one is which one ?????
( is there any special ID or something )

USB audio devices are allowed to present their input & output as separate devices, so what you can do is query each device to determine how many output channels (or input channels) it supports to determine which side (output or input) your looking at for that device.
