    hi there.
    thanks for the reply....

    My hardware is a USB FM Receiver which doesnt require any driver. Once plug in to XP/Vista, OS will automatically detect it and install it as USB FM RECEIVER.

    Which are you trying to use it on? XP? VistA? Because I see a big shiny "Designed for XP" sticker on that site, so make sure you exhaust your options there first.

    From the looks of the documentation it adds an audio device to windows which you can read from (that part wouldn't be very hard).  However their application allows you to change the freq also, meaning it is prob sending custom usb commands to the device.  With some analyzing & hacking one could possibly figure out how to reverse engineer this for your app, but I do not believe it would be trivial.
