A USB Cable Modem Network Device is typically a modem or network interface device that connects to your computer via a USB cable and allows it to access the internet through a cable broadband connection (such as cable internet service). These devices are often used in scenarios where the user doesn't have access to a traditional Ethernet port for internet connectivity or when a direct USB connection is preferred.

The USB Cable Modem Network Device Windows driver is the software needed to allow your Windows computer to communicate with the modem over the USB connection. Without the correct driver, the modem may not be recognized by Windows, and you may not be able to establish an internet connection.
