I have a Windows 7 computer. Autoplay runs happily when connecting all devices, including external drives, camera and memory sticks etc. However when I plug my IPAD 3 in to my computer via USB cable, nothing happens and it is not being "discovered". It is switched on. I am relatively new to IPAD but have gone through the various settings in it and as far as I can tell I have them set up appropriately, but maybe not? I am using an Apple adapter to connect a USB cable from the IPAD to the PC. My ultimate desire is to be able to transfer holiday pictures from my IPAD, which I straightforwardedly uploaded from my camera's memory card, to my PC.
