I am having the similar issue with the movement of my right hand. I bought the dev version and am using it with SteamVR. I have tied the Visualizer and it seams to have a hard time recognizing the right hand motions. I have been totally disappointed with the results. I am a PC enthusiast and do not mind a little trouble shooting but there are too many beta software's involved to come to any conclusion of where the problem is.
I tried calibrating the device many times and I have a difficult time to get it to 80%.
