I received mine today. I've already charged the pack & everything works fine.
[quote name='kobeisgod']Can you connect the usb cable to a computer or does it have to be the console? My computer is almost always on but my console is only on when I'm playing a game. I just got mine and I agree w/ one of the previous posts that the battery doesn't seem to fit in the way it should. It doesn't always click in and trying to remove it makes it seem like it's going to break.[/QUOTE]
I agree with all your blood, this seemed to happen with the my 1st party battery pack too. It's a tight fit. You have to press the pack down, pushing the regular battery springs, & the pressable button on top of the pack needs to pressed in firmly/all the way in while you push the pack. IMO, it's better to have a tight fit so while your moving the controller the battery pack doesn't move loosely to cause a bad connection.
As far as charging the controller through a PC usb port, I never thought of trying. If that works I could charge it through my PC, switching to my wired controller while it charges.
