BlueSMIRF do you need a usb?

I just purchased a blueSMIRF -silver and I am trying to connect it to my pc. I have read in a lot of places that you need a bluetooth usb stick to connect it to you pc. My computer has bluetooth capabilities already! do i still need the bluetooth usb stick?

No. It is bluetooth, so as long as it can pair with a master then there should be no problem.
