Pair More Devices with a Logitech Unifying Receiver

This guide shows you how to connect additional Logitech mice, keyboards, and other compatible devices to a single Unifying receiver, letting you use multiple peripherals with one USB dongle. You’ll learn the official pairing method, common pitfalls, and fixes for when things don’t work.

What You’ll Need

A Logitech Unifying receiver (usually a small USB dongle with an orange star logo).
A Logitech device that is Unifying-compatible (look for the orange star on the device or its packaging).
A computer with an available USB port.
The Logitech Unifying Software, downloadable from Logitech’s official support page. (If you have Logitech Options or Logitech G HUB installed, these may include the pairing utility.)

Step-by-Step

Install the software. If you haven’t already, download and install the Logitech Unifying Software from Logitech’s website. During installation, you may be prompted to plug in your receiver—do so if asked.
Plug in the receiver. Insert the Unifying receiver into a USB port on your computer. Wait a few seconds for the system to recognize it.
Open the Unifying Software. Launch the program. On Windows, you can find it in the Start menu; on macOS, check the Applications folder or the menu bar icon. The main window will show a list of devices currently paired to the receiver.
Click “Add Devices” or the plus (+) icon. This is usually located at the bottom left of the software window. If you don’t see it, look for a button labeled “Pair new device” or similar.
Turn on your new device. Make sure the mouse or keyboard you want to pair has fresh batteries and is powered on. For mice, move them slightly to wake them up.
Follow the on-screen instructions. The software will ask you to turn the device off and on, or to press a specific button (like the “Connect” button on the bottom of some mice). Do exactly as prompted.
Wait for the pairing to complete. The software will search for the device and display a confirmation when it’s connected. The device should now appear in the list of paired devices.
Test the device. Use the newly paired mouse or keyboard to ensure it works. If it doesn’t, repeat the process or try the troubleshooting steps below.

Common Mistakes

Using a non-Unifying receiver. Logitech also makes “Nano” receivers (without the orange star) that only work with one specific device. Check for the orange star on both the receiver and the device.
Not turning the device off and on. The pairing process often requires a power cycle to put the device in discovery mode. Skipping this step can cause the pairing to fail.
Forgetting to press the Connect button. Some devices have a small button (often on the bottom) that must be pressed to initiate pairing. The software will tell you if this is needed.
Having the device too far away. Keep the device within a few feet of the receiver during pairing.
Using the wrong software version. If you have Logitech Options or Logitech G HUB, the Unifying Software may not be the right tool. Use the software that came with your device or the latest Unifying Software from Logitech.

Tips

Label your devices. If you have several mice and keyboards, give them distinct names in the Unifying Software to avoid confusion.
Keep the receiver plugged in. The Unifying receiver supports up to six compatible devices simultaneously, so you don’t need to unplug it when switching between them.
Use the same receiver for all your compatible devices. This reduces USB port usage and lets you manage all devices from one place.
Update firmware if prompted. The Unifying Software may offer firmware updates for the receiver or devices. These can improve stability and compatibility.
Check battery levels. Low batteries can cause intermittent connection issues during pairing. Replace batteries if you suspect they’re weak.

Troubleshooting

Device not detected during pairing:

Ensure the device is Unifying-compatible (orange star).
Turn the device off and on again, then try pairing immediately.
Move the device closer to the receiver.
If the device has a Connect button, press it while the software is searching.
Try a different USB port (preferably directly on the computer, not a hub).

Pairing fails repeatedly:

Close other Logitech software (like Options or G HUB) that might interfere.
Uninstall and reinstall the Unifying Software.
Restart your computer and try again.
If the device was previously paired to another receiver, you may need to unpair it first using that receiver’s software.

Device pairs but doesn’t work:

Check if the device is recognized in the Unifying Software. If it shows as connected, try moving the receiver to a different USB port.
For mice, try a different surface (some surfaces confuse optical sensors).
For keyboards, try typing in a text field—if nothing appears, the device may be paired but not receiving power. Replace batteries.

Receiver not recognized by the computer:

Try a different USB port.
Check Device Manager (Windows) or System Information (macOS) to see if the receiver is detected.
If the receiver is damaged, you may need a replacement. Logitech sells Unifying receivers separately.

Frequently Asked Questions

How many devices can I pair with one Unifying receiver?

Up to six compatible Logitech devices can be paired to a single Unifying receiver.

Can I pair a device that already has a receiver?

Yes, but you must first unpair it from its current receiver using the Unifying Software. Then you can pair it to your Unifying receiver.

Does the Unifying receiver work with all Logitech devices?

No. Only devices with the orange Unifying logo are compatible. Older Logitech devices or those with a different logo (like the “Nano” receiver) are not.

Can I use a Unifying receiver with a non-Logitech device?

No, the Unifying protocol is proprietary to Logitech and only works with Logitech devices that support it.

What if I lost the Unifying Software?

You can download it free from Logitech’s official support website. It’s compatible with Windows and macOS.

Can I pair a device without the software?

No, the Unifying Software is required to pair new devices. However, once paired, the device works without the software running.
