The Logitech Unifying USB Receiver is a small, wireless USB dongle that allows you to connect multiple compatible Logitech devices (such as a keyboard, mouse, or other input devices) to a single receiver. The Unifying Receiver is designed to simplify the use of multiple Logitech wireless devices by pairing them with one receiver instead of needing a separate receiver for each device.

The Windows driver for the Logitech Unifying USB Receiver ensures that your computer can communicate with the receiver and the devices connected to it. It allows your computer to recognize and pair with Logitech devices, offering seamless functionality.
