Q: My iPod Shuffle doesn't appear in my iTunes, how can I get it to appear?

What have you tried so far in terms of troubleshooting this issue?  Are you plugging the iPod into a high powered USB 2.0 port on the back of your PC? Have you tried a different USB cable?

What happens if you try to reset the device with it still connected to the PC?

Has this iPod ever worked on this PC or is this the first time you have time you have tried connecting it?

Have you carefully worked through each and every single suggestion in this Apple support document?
