Ipod classic disconnects/turns off whenever it's plugged in
My Ipod classic disconnects/turns off whenever it's plugged in. I've had USB sticks in the slots and they work fine. I recently brought new charger cable so that's not the problem. I can turn it on and it works fine (although can't get anything put on there), but the second I plug it in the ipod itself shuts down or freezes and I get a message saying it's been disconnected
iPod classic, Mac OS X (10.6.8)
