I finally got my Wiz back yesterday. It turns out it was the USB cable afterall, which is what I suspected despite being told it was a faulty Wiz unit by customer service. If only they would have just sent me another USB cable as I requested, oh well. Anyway, all is good now. It charges properly. I admit I was excited when I saw the charge light come on after plugging it in for the first time. Now I can enjoy the newly ported Beats of Rage on my Wiz.
