Camera connection kit not working on ios7

Hi, ever since I updated to ios7 my camera connection kit doesn't work. I have tried it on different iPads, I have tried different connection kits on both my iPads.

What is consistent is the cck not working on ANY ipad with iOS 7. An apple shop in town tried it on their ipad with iOS 6 on it, and it was fine.

How can this be fixed? I updated to ios7.06 hoping it may be fixed by now, but no joy :(
