Ok, I know this is a problem that has had a lot of attention in the past, but despite searching here, and the internet in general for hours, I still can't seem to find a definite solution: When I plug my iPod via USB into my MacBook, it is not recognised in iTunes or on the desktop. Disk utility also doesn't appear to see it. My iPod is charged, the usb cable works, the usb ports on my Mac work too for other devices. I've tried plugging it into my Girlfriends Mac too and the same happens, nothing. I have tried the famous "5 R's" lots of times, as well as everything I have found online, and nothing is working. I really am at a loss, it's only 2 years old, hasn't been used much at all, hasn't taken any bumps, and worked fine a fortnight ago. The only thing that does happen is that when I plug it in the screen on the iPod lights up, the same happens when I unplug it too. If anyone has had the same issue and could lend a hand that'd be sweet. Cheers.
