USB Only
Does best Buy sell the USB adaptor for this keyboard? I own the keyboard and the USB adaptor broke and has been misplaced...
It comes with a Unifying Receiver, which you can pair with up to 6 other compatible Logitech accessories. I know for sure you can get one of this little dongles for next to nothing on Amazon. I'm not sure if they sell them @ Best Buy store, I'm sure they do.
If you aren't sure if the 'dongle' you are purchasing is compatible, just look for the orange square with black star like symbol, which represents that Unifying Receiver.
