Why my computer or iTunes doesn't read my iPod nano

Why my computer or iTunes doesn't read my iPod nano
The issue is that it cannot read when inserted into the laptop. It shows on the iPod that it's connected and is on the USB panel (devices connected) but I can't open the device. It's only shown as "...." It doesn't even work on iTunes or shows anywhere on the computer. Even the headphones plug in can't work. Do you know the solution?
