The PROLiNK Wireless HS-USB Ethernet Adapter 9001 is a USB network adapter that allows users to connect to a wireless network via USB. This device often functions as an Ethernet-to-Wireless converter or acts as a USB modem, providing a way to connect a computer to a Wi-Fi network when there's no built-in wireless adapter or if the built-in adapter is not functioning.

The HS-USB Ethernet Adapter 9001 generally works by presenting itself to the operating system as a network adapter (similar to a Wi-Fi card), so it needs a Windows driver to allow proper communication and use. The "Wireless" in the name suggests it is used to create a wireless connection for devices without Wi-Fi capabilities, or to share an internet connection from a computer to another device.
