I can't seem to get any recognition between the iPad and the Mac Mini. I'm using the white USB cable that came with the iPad to connect them. Tried rebooting ad nauseum. It's like two inert bodies, no indication on either side that the two are connected. No lights, sounds or animations. All the tutorials say is just connect them, and don't mention about what to do if this elementary step fails. I saw some similar questions on other forums, but distressingly, they go unanswered. Any help would be appreciated! Yimin
