If you have not already, do a Reset (restart) on the iPod
Learn how to reset your iPod - Apple Support (see section iPod with a click wheel)
If you only see the battery charging symbol on the iPod screen when you connect it, there is a power connection but no data connection. There are separate "pins" on the dock connector for power and data. The pins for power are connecting, but the ones for data are not.
One possibility is a faulty USB docking cable. To rule out faulty cable, try a different cable (if you have one), or connect the current cable do another Apple device, to confirm it's working properly.
Another possibility is a faulty dock connector on the iPod. Shine a flashlight into the dock connector, to look for any obvious damage, corrosion, dust build-up, or debris. It could be worn out from use, and no longer making proper contact.
