Seeking Powered USB hub recommendatons
Seeking recommendations: I'm looking for something that I'm having difficulty finding. I'd like to get a powered hub that is confirmed to work with iOS7 and doesn't have a lot of cables and mess. something really simple to use just for my iPad. I would rather not need a hub, but it seems that most devices require one. It doesn't need to have a lot of ports either since iOS only allows the usage of one port anyway. I'd like it to be sturdy if possible. Thanks for any and all help offered! :-)
