[Resolved] ADB No Longer Working on Android 4.2.2? - Update your ADB!
4.2.2 now enforces RSA authentication via ADB. This is only supported in later versions of ADB.

Or use 'adb version' to see if you have the latest version. ADB version 1.0.31 is working.
Google just added this in the ADB protocol last November, so you need the NEWEST ADB:

Stable builds (future?):
Please report back with the PC/Mac and possibly the cable you are using, thanks.
