@Aaron the driver is device specific so drivers won't come with the AIR SDK (maybe there is a generic one but better to have the official). For Nexus devices, you can download them with the Android SDK (link below). There will be a folder called drivers once you download. I was having the exact same issue with the 'publishing' forever issue and when you cancel, it locked up and crashed Flash CC. The only thing I did was update the driver which I believe I originally installed from the Google Android SDK.
