So I recently purchased a 4th Gen iPod Nano and plugged it into my pc to do a wipe and fresh install. However when I plug it into the computer, it causes iTunes to freeze until I unplug it. Then iTunes works just fine. I’ve tried different cables as well as usb ports and nothing seems to work. The device charges off of plugs just fine and works with the music that is already on it, but will completely lock up iTunes if I try to hook it into my pc.
