Bought this little option at WalMart in the mistaken belief that it could connect USB-2 or SD memory devices to the iPad. I think that I now understand it is ONLY for cameras, and it will not connect a USB-2 memory stick or a SD card . . . except when they are formatted by a digital camera. DUH Yeah, I know; I should have read the name more carefully, but I am now stuck with a useless device. Can these connection devices do anything else useful ? Please lay off the wisecracks now.
