is it possible to use a USB hard drive with the iPad 3? Do I need to download an app to use it (assuming I have the camera connection kit)?
You can with the iPad Camera Connection Kit, but in a very limited manner. You can import photos or videos on an external drive to the Photos app, if you set up the file structure to emulate a USB-connected camera - I believe you need a folder in the root directory named
DCIM with the photo and video files within named
.mp4, etc. as appropriate).

Hi there I have an older iPad , it's the iPad 3. I have a WHITE IPAD 1/2/3 USB ADAPTOR CONNECTION PORT KIT - Female end USB, bought from eBay. Into this I can plug in any USB device. My Apple 2002 White pro keyboard does NOT WORK due to it requiring too much power. However, my cheap as chips TRUST ( WINDOWS ) Keyboard, bought from Morrisons works... The upshot is you will only be able to get a low power USB keyboard to work, low current requirement... I have typed this out on my KB with no silly error messages.... Hope this helps !
