Q: USB IPAD 3RD

You cannot use a USB drive with your iPad. Like the warning said, it uses too much power.

You need to use a computer to import those photos to a computer and sync them in via iTunes

When I go to use my flash drive ,and input Photos to my Ipad, using my Apple photo connector, it gives me a warning.

Which "Apple photo connector" do you have? If you have this kit   http://www.apple.com/shop/product/MC531AM/A/apple-ipad-camera-connection-kit

you can use one of the adapters with an SD card directly or you can use the other adapter by connecting to your camera using USB. Neither supports file transfer from a USB flash drive.

Suggest following the instructions here:   Import photos using Apple camera adapters - Apple Support

I listen to a lot of audiobooks on my iPad. I have them on a back up drive and move them to my computer and then to the iPad...cumbersome. If I buy a new iPad is there a way to transfer my books (pics, etc) directly to and from my backup drive maybe wirelessly? Thanks.
