How to connect HARMAN KARDON SOUNDSTICKS, with USB connection, to iphone or ipod?

Not a feature of iPhone or iPod. There is no USB connection on iPhone or iPod,

and Camera Connection Kid provides connection only for limited number of uses,

such as picture transfer, and sound is not one of the uses for CCK. You will either

need an Apple dock for your device, which still will not provide USB, or use a

3rd party sound system. I have seen some powered speakers that connect

through the headphone port on an iDevice, but am not personally familiar with

any that would match the output from the HK Soundsticks.
