In addition to what Mark says: I had a similar problem with my Nexus tablet after the upgrade to 4.2.2. It was visible but any attempt at installing and launching or debugging an app silently failed - no error message at all.
As Mark's linked articles says, your device will pop up a dialog that asks for permission for that USB debugging access from your development PC. Unfortunately that popup was hidden to me because I created multiple user accounts on my tablet and the currently active account was not the "main account" that is apparently allowed to make these tough decisions. When I switched to the main account I could finally see that dialog. Surprise, surprise.
