I was using this iPod Shuffle 2nd Gen for almost 4 years without any problem, After I got iPod Touch 4G a year back, I stopped using shuffle for almost a year. When I looked at it recently, of course, to give it to my niece - it's not responding. Thinking that battery drained, I tried to charge the shuffle using the then supplied USB doc.
When connected it just blinked orange once - only once that's it. Nothing happend. Even after keeping it for a whole night, nothing happend. It doesn't play, iTunes won't recognize, but windows 7 says "USB Device not recognized", and it was showed under Generic USB Hub as "Unknown Device"
I used USB 2.0 port back of my computer.
Tried using 3rd gen shuffle charging cable, but this time not even the orange blink.
