itunes 11.1 does not see my ipod touch 4g
I updated to iTunes 11.1 today, and now iTunes does not recognize my iPod Touch 4G.
I have gone through the troubleshooting guide in Apple Support, tried multiple USB cables, uninstalled and reinstalled iTunes multiple times, and still no luck.
Windows 8 does see the Touch in the Computer window, so it appears the drivers and services are set up correctly. It just doesn't appear in iTunes at all, so I can't sync.
