    I bought the camera connection kit for my iPad 3 and whenever I use my Sony Card Reader using the USB adapter I get

    Cannot Use Device
    The connected USB device requires too much power.

    How is this possible when it is just a reader. I do not want to have to use my USB cable to import photos from my Sony camera.

    Any work arounds?

    I was hoping perhaps with the larger battery they might allow more power to be drawn. Guess not =(

    I have no idea on how to fix it. I had heard there was a jailbreak tweak to allow more power being worked on but Im not sure it was released and I cant find anything about it with a quick search.

    Is this the first iPad you are trying it on? If it worked on the 1/2 i have no idea, but otherwise I assume the same readers that work on 1/2 will work on 3 so I'd do some google searching for lists of ones that work and see if you can find one cheap. The power limit is very low, most of my usb sticks don't work.

    From random searches around it appears this issue happened after the 4.2.1 update.

    This is my first iPad. How can a simple reader use too much power? It does not even have any lights on it.

    Does anyone have any readers that works on the iPad and has a MS Duo XG slot on it.

    You will need a powered USB hub in order to use something that "requires power"
