My problem went away by itself. Seems like IPad have a problem to read data upon first use. Only thing I did differently the second time was to insert the empty connector first, and then insert the card. Nowadays it picks up the card without any hassles, regardless of the sequence of how I insert the connector and card. Just give it enough time to read the data.

They cannot access enough power fron the iPad to run and read the card. My Canon 1DMkiv will connect to the iPad and read these cards direct from the camera. I am still working on the problem with my 7D. regards David

I'm using the same spec SD card, and my IPad2 has no hassles with reading my card. It took a few attempts though to get it to work. Just leave it in for a while to read all the data. I also took the card out once, and inserted it directly in card reader of my laptop. After it worked fine on my laptop, I re-inserted it into the IPad and it worked.
