I assume you have tried everything here?
It doesn't mention 1442, but the same troubleshooting applies.
It wouldn't hurt to also try another available USB port on your machine and another sync cable if possible.
Lastly, try restoring the iPod on another PC or Mac running iTunes.
If you know of somebody with a PC running Windows XP still, ask them if you can download the reset utility and use it to reset the Shuffle.
