I don't recognize "107LL" as an iPod model. Can you identify the iPod model from this document?
In case the cause is a problem on the USB port, such as lack of available power or device conflict, you should try disconnecting all other USB devices, except for standard keyboard/mouse if normally used. If you use a USB hub, connect the iPod to a direct USB port on the computer. If your computer is a laptop, connect its power adapter (so that it is not running on battery power.
