I just got a Lumia 521 with Windows Phone 8 and am trying to get the device to work with the Zune software on my PC. I still have my Windows Phone 7 device, and the new one is not working the same way. When I plug the WP7 device into the PC's USB port, it automatically fires up Zune and I can sync my podcasts and music etc to the device. But when I plug the Lumia into the PC it doesn't fire up Zune, and if I start Zune manually, it doesn't interface with the phone at all.
Perhaps I am missing something and WP8 isn't supposed to use Zune to interface with the phone?
