How to use Bluetooth Generic Radio with Arduino

How to use Bluetooth Generic Radio with Arduino?

I have turned on with 5V of Arduino, but my PC and my phone doesnt detect it :(

This is like it: http://printerwirelessnetwork.1st-printer-ink-cartridges.com/new-micro-usb-bluetooth-2-0-wireless-dongle-adapter-windows-vistaxp2000-plug-and-play/

That device is a USB slave. It is intended to be plugged into a USB master. The Arduino is also a USB slave. USB slaves only listen to USB masters.

Do you know any bluetooth usb master cheap?
