Indeed, Android 4.2.2 introduced a change in the ADB protocol for security purposes which broke compatibility with the IOIO. Since Android 4 and up all support AOA, I've never bothered changing the ADB implementation on the IOIO to support the new protocol. So what you're seeing is the normal behavior.
Do you have a good reason to not using AOA? There seem to be mostly benefits to doing so (better performance, not having to enable USB debugging, automatic launching of the app).
