Regarding this adapter: http://store.apple.com/us/product/MD098ZM/A Would it be possible to connect a USB keyboard through the 30-pin connection? I know I probably wont find someone who knows without a doubt; but based on existing functionality of the 30-pin connector is it possible? In other words, has anyone "created" their own CCK by modifying a standard 30-pin cable? In case you're wondering (and I'm sure you are), I am looking to connect my jailbroken iP4 to a Motorola Lapdock for mirroring. I already have the adapter to connect a standard HDMI to the Lapdock's micro-HDMI female. Therefore if I am able to also connect from the 30-pin to the micro-USB input (with 5v removed) I could gain functionality of the built in keyboard. The Lapdock's built in keyboard acts as a USB keyboard by default. The whole setup is going to be mostly for proof of concept and to hopefully replace my netbook. BTW I have a host of Cydia apps that would compliment the arrangement; i.e. displayout, btstack mouse, touchpose, activator, etc..
