How to sync logitech mouse to dongle

Last Updated: Feb 17, 2024 by

Logitech is a well-known brand for computer peripherals, and their wireless mice are no exception. These mice come with a small USB dongle that allows them to connect to your computer wirelessly. However, if you lose or replace the dongle, you may need to sync your mouse to a new one. In this article, we will discuss how to sync your Logitech mouse to a dongle.

Check Compatibility

Before attempting to sync your Logitech mouse to a new dongle, it is important to check if they are compatible. Logitech uses a proprietary wireless technology called “Unifying” for their mice and dongles. This means that only Logitech Unifying devices can be synced together. If your mouse and dongle are not both labeled as “Unifying,” they will not be compatible.

Download Logitech Unifying Software

To sync your Logitech mouse to a new dongle, you will need to download the Logitech Unifying software. This software is available for free on the Logitech website and is compatible with both Windows and Mac operating systems. Once downloaded, follow the instructions to install the software on your computer.

Connect the Dongle

Once the software is installed, insert the new dongle into a USB port on your computer. The dongle should be recognized by the software and appear in the list of available devices. If it does not, try using a different USB port or restarting your computer.

Put the Mouse in Pairing Mode

Next, you will need to put your Logitech mouse into pairing mode. This will allow it to connect to the new dongle. The exact method for putting your mouse into pairing mode may vary depending on the model, so refer to the user manual for specific instructions. In most cases, you will need to hold down a button on the bottom of the mouse for a few seconds until the LED light starts flashing.

Pair the Mouse to the Dongle

Once your mouse is in pairing mode, open the Logitech Unifying software on your computer. Click on the “Add Devices” button and follow the on-screen instructions to pair your mouse to the new dongle. The software will search for available devices and should detect your mouse. Once the pairing is complete, the LED light on your mouse should stop flashing and remain solid.

Test the Connection

To ensure that your Logitech mouse is properly synced to the new dongle, test the connection by moving the mouse around and clicking the buttons. If the cursor moves and the buttons respond, then the connection was successful. If not, try repeating the pairing process or contacting Logitech customer support for further assistance.


Syncing your Logitech mouse to a new dongle is a simple process that can be done in just a few minutes. By following these steps, you can easily connect your mouse to a new dongle and continue using it wirelessly. Remember to always check compatibility and use the Logitech Unifying software for the best results. Happy syncing!
