Since I upgraded my iPad 1 to iOS 5.1 and my macmini to Os Lion, the OS Lion does not recognize my iPad when it is plugged in. iTunes will usually recognize it, though after some time has passed. Sometimes it does ot seem to recognize the iPad at all. And I no longer get the usb bleep when I plug it in. I am running Bootcamp with Win 7 on that side of the "duplex". There, when I plug in my iPad I get a warning that the device is not recognized---and that Win can't install the proper driver. Can anyone steer me in the direction of a solution? Thans.
