1st generation ipod touch won't sync with itunes
i recently bought an original ipod touch off someone, synced it to my computer and it worked the first time, it's a 16gb and had about 200 songs on it. I go to plug it in today and my mac says "getting invalid response" from the device and i have no idea what to do. I tried restarting everything, even restoring the ipod to factory settings but nothing has worked. Every time i plug it in it makes a weird little beep noise then it pops up that it has a "invalid response" can anyone help me?
