iPad 2 not charging when attached to computer USB

[XtrGamer]

Dear Experts,
                 
I own an iPad 2 and when I connect it via USB port to the CPU it says not charging. So far I have only been Ble to charge it by connecting it to a power socket thru the power cord but cant I charge it thru the computer too like how I charge my iTouch? It would become much more convenient. Please help.

The iPad requires 10 Watts to charge.
If you have an Asus computer, you can use Asus Ai Charger to provide the 10W necessary through the USB ports. If you have an MSI computer, you can get MSI i-Charger to do the same thing. If you have a Gigabyte computer, you can use Gigabyte ON/OFF charge.

EDIT: http://event.asus.com/mb/2010/ai_charger/ "Compatible with All Motherboards and PCs!" Give it a try.

I have come across something similar with an iPod Shuffle.
It wouldn't charge until I got iTunes.
Make sure you have got that and post back.

... the OP has already said that the problem is solved... also the fact that he already owns an iPod touch means that he already has iTunes installed...
So I'm marking this "Solved."
