I know the 2nd gen Touch is really old but I liked using it and it was a handy device to have separate from my phone. Anyway it was working fine until literally 2 days ago when iTunes stopped detecting it. Note I hadn't updated iTunes around that time, but I just suddenly got the message "iTunes could not connect to the iPod touch “iPod touch” because an invalid response was received from the device." I have swapped USB cables, swapped ports, done a soft reset on the iPod, restarted the Mac. Then, as a last resort I did a complete reset and erase on the Touch. (This was a mistake as the iPod was functioning fine, it just wouldn't update. Now I have no music on it at all). Anyone know a fix for this. The Ipod is still a perfectly useful gadget as far as I'm concerned. Shame to trash it.
