Help with setup: Mouse is not working
1. Is the mouse powered on?
2. Is the Unifying receiver securely plugged into a computer USB port? Try changing USB ports.
3. If the Unifying receiver is plugged into a USB hub, try plugging it directly into a USB port on your computer.
4. Check the orientation of the batteries inside the mouse. To check battery power, turn the mouse OFF and then ON. If the battery indicator light glows red or does not glow at all, replace the batteries.
5. Try using the mouse on a different surface. Remove metallic objects between the mouse and the Unifying receiver.
6. Try moving the Unifying receiver to a USB port closer to the mouse. If you are using a tower PC, go to www.logitech.com/usbextenderfor a USB extender.
7. Try reconnecting the mouse and Unifying receiver using the Logitech Unifying software (refer to the

The Logitech® Unifying receiver
Plug it. Forget it. Add to it.Your new Logitech product ships with a Logitech® Unifying receiver.
Did you know you can add a compatible Logitech wireless device that uses the same receiver as your current Logitech Unifying product?

Are you Unifying-ready?If you have a Logitech wireless device that’s Unifying-ready, you can pair it with additional Unifying devices. Just look for the orange Unifying logo on the new device or its packaging. Build your ideal combo. Add something. Replace something. It’s easy, and you’ll use only one USB port for up to six devices. Getting started is easyIf you’re ready to pair your device(s) via Unifying, here’s what you need to do:

1. Make sure your Unifying receiver is plugged in.
2. If you haven’t already, download the Logitech® Unifying software from www.logitech.com/unifying.
3. Start the Unifying software* and follow the onscreen instructions to pair the new wireless device with your existing Unifying receiver. * Go to Start / All Programs / Logitech / Unifying / Logitech Unifying Softwar

Logitech Unifying receiver (Older)

Logitech Unifying receiver (Newer)

The Logitech Unifying receiver is a small dedicated USB wireless receiver, based on the nRF24L-family of RF devices,^[1] that allows up to six compatible Logitech human interface devices (such as mice, trackballs, trackpads, and keyboards; headphones are not compatible) to be linked to the same computer using 2.4 GHz band radio communication. Receivers that are bundled with a Logitech product are paired with the device at the factory. When purchasing a replacement receiver or connecting multiple devices to one receiver, pairing requires the free-of-charge Logitech Unifying software, available for Microsoft Windows and Mac OS X. Although not compatible with Bluetooth, devices pair to Unifying Receivers in a similar way.^[2] Peripherals remain paired, and can then be used on systems not supporting the software. Logitech receivers compatible with the Unifying protocol can be identified by the orange Unifying logo, which distinguishes them from Logitech Nano receivers of similar appearance, which pair in a similar manner but only with a single device, without using the Unifying protocol.

Logitech Unifying receivers (LURs) are often included in wireless Logitech keyboard, mouse, and combo sets, and may be purchased separately. Some Logitech peripherals allow a receiver to be stored inside.^[3]

As of October 2019 Logitech Unifying Software for Windows had last been updated, to version 2.50.25, on 30 March 2010.^[4]

Compatibility and use[edit]

Each peripheral device can pair to one receiver per profile. While most peripherals only store one profile, newer products such as the Logitech MX Master, MX Anywhere series, and M720 Triathlon allow multiple profiles. These devices can be connected to multiple receivers simultaneously. This allows the use of receivers in several computers, e.g., a desktop and a laptopcomputer, selecting the computer to use by changing profiles on the mouse. This multi-computer function is further augmented by Logitech Flow (software KVM solution) which is similar to Synergy. For devices without multi-computer support, the receiver and input devices can be moved together from one computer to another, maintaining their paired status after being unplugged, as the pairing information is held in the little USB receiver^[2]—this is much simpler than transferring the peripheral from one receiver to another by changing the setup in software, and also avoids the limitation to 45 pairings of older devices. This also allows the use of peripherals on computing devices that do not support Unifying Software, e.g. devices supporting USB OTG with operating systems such as Android: first pair to the receiver on a PC or Mac.^[5]

Some older Unifying devices limit the number of allowable pairing changes to a maximum of 45 times. Once the 45th connection is made, it is no longer possible to connect such a device to a different receiver. For users who often switch a Unifying device between multiple PCs or laptops with individual receivers, this connection limit can become an issue. For example, a user who frequently switches a mouse between two receivers (e.g. at work and home) will quickly exhaust the limit of available pairing switches.^[6] Logitech advises customers with this issue to contact their Customer Care. Newer devices can switch pairings an unlimited number of times.

Pairing software is available from Logitech for Microsoft Windows and Mac OS X. Wireless devices using the Unifying Receiver are supported since Linux 3.2.^[7]Software to manage Unifying devices on Linux is available from third party developers, such as Solaar.^[8]

Many companies have made peripherals that connect via USB wireless receivers very similar to Logitech's; Logitech devices are incompatible with many of these 'off-brand' receivers^{[citation needed]}.

There are many different hardware versions of the unifying receiver. The most common is used for daily use, and is marked ^[9]CU-0007 on the metal jacket. CU-0008 is distributed with gaming devices, and features lower latency.

Security[edit]

Several security vulnerabilities of the Logitech Unifying system have been reported in 2016 and 2019,^[10] and patches released.

MouseJacking and keyjacking[edit]

MouseJacking, first reported by Bastille Networks, Inc.,^[10] is the sending of malicious radio signals (packets) wirelessly to an unsuspecting user through Logitech Unifying wireless technology. The exploit takes advantage of a user's vulnerable Logitech Unifying receiver and unencrypted signals within a range of about 100 meters. Possible exploits include:

Keystroke injection by either spoofing a paired mouse or keyboard
Forced pairing
