Wired keyboard for iPad Mini Is there any wired keyboard-case available for new iPad Mini (thefore using Lightning port)? Or keyboard-case with standard USB cable, that has been tested and proven to work with Lightning OTG Adapter? Does anyone have any experience in this area to share?

I did a really good (as I think) research on this in the Internet, but all I've found is a really big bunch of wireless Bluetooth-based keyboard-cases for iPad Mini. Plus some entries that only suggest that a wired keyboard-case should work.

I don't like the entire idea of charging keyboard aside of charging iPad itself. So the best solution for me would be either keyboard-case with Lightning cable or keyboard-case with standard USB plug, proven to work with iPad Mini through OTG adapter.

Thank you in advance for any help here.
Nope, it won't work. Apple disabled the functionality a while ago with an iOS update. It only worked for few months on the first iPad with the Camera connection kit.

I tested it on my iPad 2. If I remember well, when connecting an Apple USB keyboard it poped a message that said the connector can't provide enough power ... Probably a fake reason because it worked before.
