When Apple first revealed the $30 iPad Camera Connection Kit, which contains a little dongle that allows you to use a USB 2.0 cable to transfer photos from your camera to your iPad’s iPhoto library, a lot of people wondered if it might be used to connect other USB devices as well.
As it turns out, you can: you can use the Camera Connection Kit to hook up an audio headset and a USB keyboard.
Not terribly exciting, but as the Camera Connection Kits begin to be shipped, it might hint at more exciting USB interoperability to come. A game pad certainly would be nice.
