How do I charge my iPad via USB?
I've just got a new iPad (version 1) and I am trying to charge it up with the USB cable connected to my computer. When I plug it in, it says "not charging" at the top right. I read elsewhere that it charges via USB 2, but it just doesn't seem to be happening. The port I plugged it into on my computer says USB 2 on it, so I think I am doing the right thing.
