The Intel(R) USB Client Ethernet Device is a USB-based Ethernet adapter, typically used to enable network connectivity via a USB port. These devices are useful when you need to add Ethernet (wired) network functionality to a device that only has USB ports, such as a laptop, tablet, or embedded system. The Intel(R) USB Client Ethernet Device driver enables Windows to properly communicate with this Ethernet-over-USB device, allowing it to function as a regular network adapter.
