I connected my phone to try to put some new music on it, but it isn't being recognised as a device? It's charging and I've tried several different cables and it hasn't changed anything, so it's definitely not an issue with the USB connection. I restarted the apple mobile device service, still won't work. I have windows 8 if that affects anything. I've restarted both iTunes and my computer several times, still won't work, and my version of iTunes and iOS are definitely up to date. It won't sync and the device bar doesn't show up, also the disconnecting button on the task bar which shows up for all devices isn't showing up… Can anyone help me?!
