I just ran into an issue that is a first for me in my 10 years of iPod ownership. My iPod nano was booting up from "deep slumber" when I plugged it in. It showed the Lightning cable with "Eject Before Disconnecting". Then it immediately changed to "OK to disconnect". Never showed up in iTunes, nothing. I unplugged it and plugged it back in and saw it appear on my desktop for a quick second until iTunes tried to pick it up and it ejected itself again. I have tried another Lightning Cable, another USB port, a fresh install of iTunes, a new user, another iTunes library and nothing, I mean NOTHING has been able to get this thing mounted in iTunes. I even Reset All Settings (the only option available on this model), nada. So I'm prepared to call Apple tomorrow but was wondering if anyone here had any ideas of what to try? I'm running 10.10.1 Yosemite with iTunes 12.0.1 and iPod nano SFTW 1.0.3.
