I have purchased a camera kit which contains a USB port but I keep getting a message saying the USB is using to much power so it is unable to work? Funny that! because it still manages to read the DCIM folder as long as it has only photos in it. Won't show the other contents such as a PDF or word document. I'm so annoyed as my husband's Galaxy Tab 10.1 reads everything on the USB. Is there anyway around this? I have IOS 5.01.
