So far connecting a USB drive has only been possible if you jailbreak the iPad, now since we are not going to post anything on here about jail breaking the iPad here is a way you can transfer files from the USB drive to the iPad without jail breaking it first,
For this to work you will need the following:
– iPad Camera Connection Kit
– USB thumb drives
When you have both of the above, then this is what you need to do in order to import photos and videos onto your iPad.
1. take the thumb drive and create a folder on it named DCIM.
2. Next, copy the photos and video you want to import into the Photos app on your iPad into that particular folder.
3. Finally, plug the USB thumb drive into the Connection Kit.
If you do this correctly The iPad will recognize the thumb drive as if it were a camera and import the photos and videos.
