Which USB keyboards will work with an iPad 3? It is possible to connect a USB keyboard to an iPad (3rd generation) using the camera connection kit. 

However, my Apple keyboard does not work so which ones do? 

Yes I know I could buy a wireless keyboard.
Yes you can, but it doesn't seem to work under the new iOS6.
