Hi CDRRodriguez,
If your iPod nano is having difficulty syncing with your computer you may want to try the steps outlined in this article -
iPod nano (7th generation): Hardware troubleshooting

Specifically -
iPod not recognized by iTunes or computer
Make sure you have installed the latest iTunes software from www.itunes.com/downloads. Try connecting to a different USB port on your computer. Your computer needs a USB 2.0 port or a USB 3.0 port to connect iPod nano. If you have a Windows PC that doesn't have a USB 2.0 port, in some cases you can purchase and install a USB 2.0 card.
- If iPod nano is connected to a USB hub, try connecting iPod nano directly to your computer's USB port.
- iPod nano might need to be reset. Reset iPod by holding down the Sleep/Wake button and Home button until you see the Apple logo appear.
- If you're connecting iPod nano to a portable computer using the Lightning Cable, connect the computer to a power outlet before connecting iPod nano.
- Check the cable connections. Disconnect the cable at both ends and make sure no foreign objects are in the USB ports. Then reconnect the cable.
- Try reinserting the Lightning connector into the iPod. The Lightning connector can be inserted either way.
- Try restarting your computer.
If none of these steps resolves the issue, you might need to restore the iPod nano software.
