Yeah the only one I have but my son has one too. I got two when I ordered mine. One for me and you guessed. My sons worked out of the box but mine has never functioned correctly. I tried as you suggested Thomas. No joy sadly, though I did manage to make a connection to both Slushy's pool and Eclipse but the unit never hashed anything. That was the first time it has managed to do so. I now believe I got a none functioning unit.
