Help with the plug and play kit!

I just bought a plug and play kit for my wireless controller. The directions say that the light on the cord should glow red, and turn green when it's fully charged and ready to play wirelessly, but my light won't come on at all. It's green for almost 1/3 of a second as I plug it in. After that, it doesn't light up. I've plugged it in every USB port on my 360. I've plugged it in before and after booting up the 360. I've unplugged and plugged the cord. I'm running out of ideas. And the controller won't play without the wire, so I know it's not charged. So am I doing something wrong? What am I missing here?

Plug it into your controller, it will flash, then turn off. It charges while you play, but when your finish playing. Just simply turn off the power and it will turn off for a second, then it will turn red meaning it's charging.

Yes I have the battery pack inserted. I hope it's not defective. Can the security device disabler mess with it at all? Because on my way out of the store I set off the alarm. The guy at the door went nuts on the thing with that scanner doohickey.
