IntroducedAugust 4, 2009; 16 years ago (2009-08-04)[1]
TypeWireless dongle
Connection2.4 GHz RF communication
PortsUSB Type-A

The Logitech Unifying receiver is a small dedicated USB wireless receiver, based on the nRF24L-family of RF devices,[2] that allows up to six compatible Logitech human interface devices (such as mice, trackballs, touchpads, 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 macOS. On Linux, the Solaar software can be used to adjust the configurations. Although not compatible with Bluetooth, devices pair to Unifying Receivers in a similar way.[3] 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 similarly 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.[4]

A newer receiver named "Logitech Bolt" was released in 2021 that promises lower latency but is incompatible with Unifying products.

Compatibility and use

[edit]
An older design for the USB receiver

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 laptop computer, 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[3]—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 [specify] 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 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 were reported in 2014 and 2019,[9] and patches released.

MouseJacking and keyjacking

[edit]

MouseJacking, first reported by Bastille Networks, Inc.,[9] 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 spoofing either a paired mouse or keyboard
  • Forced pairing

Response

[edit]

Logitech has released Unifying receiver firmware updates as new exploits were reported.[15][16]

Linux users can use fwupd to flash an updated firmware. It will automatically detect available updates for any connected unifying receivers and many other firmware updatable devices. An outdated alternative is MouseJack.[2]

Flashing on a Linux/UNIX host via a hypervisor such as VirtualBox along with a Windows virtual guest image and the Windows Logitech update executable is also possible. If using a Windows virtual guest, it is recommended to have a second available pointing device while the dongle is being updated. The second pointing device may be needed to allow the user to select and enable pass through of the unifying receiver via the hypervisor task bar after executing the firmware updater so that the device is found and updated.

Updating the Unifying receiver firmware to versions RQR12.08 or greater and RQR24.06 or greater can limit some functionality of certain paired devices unless the devices' firmware is also updated.

Other vulnerabilities

[edit]

On July 9, 2019 another set of vulnerabilities was disclosed and documented by a different researcher.[9] A firmware update for Unifying receivers addressing the "Encryption Key Extraction Through USB" vulnerability (CVE-2019-13054/55) was released on 28 August 2019.[16] Some users reported in 2019 that some Unifying devices were still being sold that were vulnerable to the original 2016 MouseJacking attack.[17]

Logitech Unifying receiver

View on Grokipedia
from Grokipedia
The Logitech Unifying receiver is a compact USB receiver designed by to connect up to six compatible keyboards, mice, and other peripherals to a single computer using advanced 2.4 GHz technology. This tiny device, which plugs into a USB Type-A port and remains connected without obstructing other ports, enables seamless pairing and operation of multiple devices while minimizing cable clutter and the need for separate receivers. Introduced in August 2009, it was developed to consolidate input from 's expanding lineup of peripherals into one efficient USB solution, supporting a reliable connection range of up to 10 meters (33 feet) with virtually no delays or dropouts. Key features of the Unifying receiver include easy device pairing through 's Logi Options+ software, which allows users to customize settings, manage connections, and switch between devices effortlessly. It is compatible with a wide range of products marked as "Unifying ready," such as the MX series mice and K-series keyboards, making it ideal for multi-device setups in home, office, or mobile environments. The receiver's design emphasizes portability and convenience, as it can stay plugged into laptops during travel and supports secure, interference-free communication in the 2.4 GHz band. Over the years, has iterated on the receiver's form factor to make it even smaller while maintaining with earlier Unifying devices.

Introduction and History

Development and Launch

The Unifying receiver was developed in the late by to address the growing issue of USB port clutter caused by multiple dedicated receivers for peripherals such as keyboards and mice. Prior to its introduction, users often required separate USB dongles for each device, leading to limited port availability on computers and laptops. The receiver was officially launched on August 4, 2009, through a press release that highlighted its ability to consolidate up to six compatible devices into a single USB port. This nano-sized was positioned as a solution for simplifying wireless setups, particularly for office and home users managing multiple input devices. At its core, the Unifying receiver utilizes technology based on Nordic Semiconductor's nRF24L-series RF chips, enabling reliable 2.4 GHz communication between the receiver and paired peripherals. Early emphasized its role in reducing USB port consumption while maintaining compatibility with Logitech's existing ecosystem for keyboards and mice.

Evolution and Iterations

The 2009 launch featured a compact nano form factor for the Unifying receiver, designed as a leave-in USB to minimize interference with portability while maintaining reliable 2.4 GHz connectivity. Subsequent hardware iterations have included variations in form factor, such as larger designs to enhance antenna performance and signal range in congested wireless environments, along with refinements to ultra-compact variants for permanent installation without removal. On the software side, released the Unifying Software in early to facilitate device pairing and , initially supporting Windows and macOS with subsequent updates expanding compatibility, including stability improvements and broader operating through versions like 2.52.x in 2022. As of 2023, the software continues to receive updates, such as version 2.52.33. Pairing capabilities evolved as well; early receivers were limited to 45 unique device pairings over their lifetime due to firmware constraints, but later models removed this cap, enabling unlimited pairings via updated firmware while retaining the standard limit of six simultaneous active connections.

Technical Specifications

Hardware Components

The Unifying receiver is a compact USB that serves as a interface for compatible Logitech peripherals. Its form factor emphasizes portability, with the Nano version measuring approximately 18.7 mm in height, 14.4 mm in width, and 6.1 mm in depth, allowing it to remain plugged into a USB port without significant protrusion. The device uses a standard USB Type-A connector for compatibility with most computers, and no native variant exists as of 2025. Power for the receiver is supplied entirely through the USB 2.0 interface at 5 V, eliminating the need for any external battery or additional power source. This design ensures low overall power draw, suitable for continuous operation in standard USB ports. Internally, the receiver incorporates the , which handles the 2.4 GHz operations, along with an integrated antenna for compact signal transmission. Compatible Logitech devices and packaging are identified by the distinctive orange Unifying logo, a star-like symbol that differentiates it from other receiver types such as the standard Nano receiver. This marking confirms adherence to the Unifying protocol and aids users in verifying hardware suitability.

Wireless Communication

The Logitech Unifying receiver operates in the 2.4 GHz band, utilizing a proprietary protocol layered on the nRF24L chipset family developed by . This frequency range spans 2400–2525 MHz with 1 MHz channel steps, enabling unlicensed operation while avoiding overlap with other common wireless standards. The protocol, known as HID++ 1.0, handles device communication over this band, supporting input events from peripherals like mice and keyboards. The receiver achieves a reliable operational range of up to 10 meters (33 feet) in line-of-sight conditions, leveraging the nRF24L's enhanced sensitivity and output power capabilities. To mitigate interference in the crowded 2.4 GHz , the system incorporates channel hopping mechanisms; if a packet times out, the receiver and device automatically switch channels, adapting to environmental noise from sources like or microwaves. This adaptive approach ensures consistent performance without requiring user intervention, though it does not employ the full spread- frequency hopping seen in standards like . Data transmission occurs at configurable rates of 250 kbps, 1 Mbps, or up to 2 Mbps, optimized for low-latency input applications such as cursor movement and keystrokes. The higher rates prioritize responsiveness, with acknowledgment payloads enabling bidirectional communication and reducing retransmissions. In practice, the 2 Mbps mode supports near-real-time event delivery, essential for gaming or productivity tasks. The connection topology is one-to-many, allowing a single receiver to pair with up to six compatible devices simultaneously. Bandwidth is shared via (TDMA), where devices transmit in assigned time slots to avoid collisions, managed by the receiver's scheduling of keepalives and data packets. This efficient maintains low overall latency across multiple peripherals without dedicated channels per device.

Compatibility and Pairing

Supported Devices and Limits

Logitech does not publish an official comprehensive compatibility list for the Unifying receiver. Devices are compatible if they feature the orange Unifying logo (a six-point star symbol) on the device itself (often on the bottom) or its packaging. The Logitech Unifying receiver supports up to six compatible Logitech wireless human interface devices, primarily mice, keyboards, trackballs, and touchpads. A single Unifying receiver allows up to six devices to be connected simultaneously, enabling users to pair multiple peripherals to one USB port without interference. The Logitech Unifying receiver is compatible with a range of wireless peripherals designed for the 2.4 GHz protocol, including mice such as the Marathon Mouse M705 and MX Master 2S (pre-2021 models), keyboards like the Wireless Illuminated Keyboard K800 and Wireless Combo MK270, as well as trackballs such as the Wireless Trackball M570. Regarding pairing constraints, legacy Unifying devices are restricted to a maximum of 45 total pairings over their lifetime, after which further re-pairing becomes impossible; however, most Unifying devices do not impose this limit. The Unifying receiver is not cross-compatible with devices designed exclusively for Logi Bolt receivers or Bluetooth-only connectivity, requiring separate receivers for those ecosystems. Newer Logitech devices may use Logi Bolt instead, which is incompatible with Unifying receivers. Once paired on a PC, Unifying devices can also function with mobile devices via USB OTG adapters.

Operating System Integration

The Logitech Unifying receiver integrates natively with Windows operating systems, where it is recognized automatically as a standard USB HID device upon insertion, enabling basic functionality without additional drivers. For advanced features such as device pairing and customization, Logitech provides the Logi Options+ software, which supports the Unifying receiver on Windows 10 and later versions. Although the legacy Logitech Unifying Software offered similar capabilities, Logitech has discontinued its maintenance and recommends transitioning to Logi Options+ for ongoing support. On macOS, the Unifying receiver has offered full pairing and management functionality since version 10.7 through the original Logitech Unifying Software, allowing users to connect and configure compatible peripherals directly. Current integration is handled via Logi Options+, which provides comprehensive support for Unifying devices on macOS 13 (Ventura) and later, including seamless detection and customization options. This software ensures compatibility with modern macOS features while maintaining backward compatibility for legacy Unifying hardware. Linux users rely on third-party open-source tools for full integration, as Logitech does not provide official drivers or software. The Solaar application serves as a robust manager for Unifying receivers, enabling pairing, unpairing, battery monitoring, and configuration adjustments without requiring proprietary drivers; it operates effectively on Linux kernels 3.0 and newer across major distributions. Basic receiver functionality is handled natively by the Linux kernel's HID subsystem, ensuring plug-and-play operation for supported devices. For mobile platforms, the Unifying receiver can connect to Android devices via USB OTG adapters, leveraging standard HID protocols for input functionality once devices are paired. Similarly, iOS devices support it through Lightning-to-USB Camera Adapters, though both require initial pairing and configuration on a Windows or macOS computer due to the absence of native mobile software. This setup allows up to six devices to operate, but limits advanced management to desktop environments.

Usage and Software

Pairing Procedures

The pairing process for the Logitech Unifying receiver uses Logitech's Logi Options+ software, as the legacy Unifying Software is deprecated and no longer supported or maintained by Logitech. Logitech highly recommends using Logi Options+ for pairing and managing Unifying devices. Logi Options+ is available for download from Logitech's website and compatible with Windows and macOS operating systems. The legacy Unifying Software may still function for older setups but is no longer supported or maintained by Logitech. To begin, install Logi Options+ on the computer, then insert the Unifying receiver into an available USB port; the software will detect the receiver automatically upon launch. Next, select the option to add a device within the software interface, which prompts the user to press and hold the connect button—typically located on the bottom of the compatible device—until an LED indicator begins flashing, signaling pairing mode. Follow the on-screen instructions to complete the connection, after which the device should respond immediately, such as by moving the cursor or typing on a keyboard for verification. This procedure allows up to six compatible devices to be paired to a single receiver, with each occupying a dedicated slot. To unpair a device from the Unifying receiver, launch Logi Options+ and navigate to the device management section, where the paired devices are listed. Select the specific device to remove, confirm the action in the prompted dialog, and the software will release the pairing slot for reuse with another device. If necessary, resetting all pairing slots can be achieved by removing all devices through the software, though this may require re-pairing all devices afterward. Common troubleshooting issues during pairing include the receiver not being detected, which can often be resolved by trying a different USB port on the computer, ensuring no is used, or restarting the computer to refresh connections. If a device fails to respond after pairing, verify that batteries are properly installed and charged, test on a non-metallic surface to avoid interference, and check for updates via Logi Options+, which automatically scans and applies necessary updates to the receiver and devices. In cases of persistent connectivity problems, removing metallic objects between the device and receiver or repositioning the receiver closer to the device may help mitigate signal interference. In multi-receiver scenarios, a Unifying-compatible device can be switched to a different receiver by first unpairing it from the original receiver using the software, then repeating the process with the new receiver, as each receiver maintains its own independent slots limited to six devices. This re-pairing ensures compatibility but requires the software to be installed on the target computer.

Device Management Features

The Logitech Unifying receiver integrates with Logi Options+ software (which supersedes the deprecated legacy Unifying Software), providing a centralized that displays all paired devices, their connection status, and options for reconfiguration such as unpairing or reassigning channels. This interface allows users to view up to six compatible peripherals connected to a single receiver, facilitating easy oversight without physical inspection of each device. Battery monitoring is a key feature, offering real-time indicators of power levels for connected mice, keyboards, and other devices directly through the software, which helps prevent unexpected by alerting users to low battery conditions. For instance, the dashboard provides percentage-based readouts and notifications, ensuring proactive management of device longevity across the Unifying ecosystem. Devices in the series, such as the MX Master and MX Keys, support multi-computer connectivity, enabling seamless switching between up to three systems via dedicated Easy-Switch buttons on the hardware or through software profiles in Logi Options+. This allows users to pair the device with multiple Unifying receivers—one per computer—and toggle connections effortlessly, enhancing workflow across setups without repeated pairing. Customization options within the software extend to button remapping and sensitivity adjustments, such as DPI settings for mice, tailored to individual preferences and applications via intuitive profiles. These tools enable users to reconfigure inputs for specific tasks, like assigning shortcuts or optimizing scroll behavior, all managed post-initial through the Unifying receiver's ecosystem.

Security Analysis

Identified Vulnerabilities

The MouseJack vulnerability, disclosed in 2016, affects Unifying receivers and enables remote attackers to inject keystrokes into paired keyboards and mice by exploiting unencrypted control packets in the 2.4 GHz wireless protocol. This attack bypasses the protocol's AES-128 encryption for keystroke data, allowing injection without knowledge of the session key, as the receiver processes unauthenticated packets from nearby transmitters within approximately 100 meters. Devices with USB vendor ID 046D and product ID C52B, a common identifier for Unifying receivers, are particularly susceptible to this flaw. In 2019, researcher Marcus Mengs identified four additional flaws in the Unifying protocol (CVE-2019-13050 through CVE-2019-13055), including CVE-2019-13055, which permits attackers with brief physical access to extract AES encryption keys from the receiver using tools like the Crazyradio PA . This extraction involves sniffing pairing traffic or directly querying the receiver via USB, enabling decryption and replay of subsequent communications, including keystrokes and movements. versions prior to RQR24.06 lack protections against such key recovery, amplifying the risk of man-in-the-middle attacks on encrypted links. These vulnerabilities impact a range of Unifying-compatible devices, such as the M705 wireless mouse with firmware up to 2016 releases and the K800 , where unpatched receivers allow unauthorized keystroke interception and injection. All Unifying receivers prior to post-2019 firmware updates are affected, as the protocol's design permits passive during or active exploitation of radio channels. As of 2025, residual exploits persist in unpatched older Unifying hardware or after downgrades, where attackers with brief USB access (approximately 30 seconds) can reset the receiver to vulnerable and extract keys to enable real-time keylogging by decrypting radio transmissions. This method grants full control over input devices, allowing injection of malicious commands without further wireless proximity after initial access.

Mitigation Measures

In response to the 2016 MouseJack vulnerability disclosed by Bastille Research, which allowed key injection attacks on unencrypted packets, Logitech released firmware update RQR12.08 for the Unifying receiver. This update implemented packet encryption to prevent unauthorized keystroke injection from nearby attackers. Following the 2019 discovery of additional flaws by security researcher Marcus Mengs, including weaknesses in key negotiation that enabled key extraction and keystroke injection up to 100 meters away, Logitech issued firmware version RQR24.06. This patch reinforced the key negotiation mechanism to mitigate extraction risks, though it did not address all identified issues. Post-2021, has delivered incremental patches through the Logi Options software. As of mid-2024, updates prevent direct key extraction via USB access but do not block downgrades, leaving the exploitable with brief physical access to reset the receiver. These updates require physical connection of the receiver and are designed to enhance overall . No significant changes to this status have been reported as of November 2025. To minimize risks, users should regularly update firmware and associated software via official Logitech tools, refrain from using Unifying receiver devices in public or unsecured environments where brief physical access could be gained, and opt for wired peripherals during sensitive operations such as handling confidential data.

Third-party protocol implementations

Community projects have explored implementations of the Logitech Unifying protocol on microcontrollers such as the ESP32. The primary method involves connecting an NRF24L01+ module to the ESP32 via SPI to emulate the Unifying protocol, thereby enabling the connection and control of compatible Logitech devices such as mice and keyboards. Libraries originally developed for the ESP8266 can be adapted for the ESP32. Additionally, models such as the ESP32-S3 support direct connection of the Unifying dongle using their USB host capabilities, though this approach requires custom software implementation to handle the proprietary protocol.

Legacy and Comparisons

Relation to Logi Bolt

The Logitech Unifying receiver employs a proprietary 2.4 GHz radio frequency protocol developed by Logitech for wireless connectivity, whereas Logi Bolt utilizes Bluetooth Low Energy (BLE) 5.0 or higher as its foundational technology, incorporating AES-128-CCM encryption for enhanced data protection. Logi Bolt introduces significant security improvements over Unifying by mandating authenticated pairing through mechanisms like Elliptic Curve Diffie-Hellman (ECDH) P-256, which prevents unauthorized device connections, and it natively resists vulnerabilities akin to the MouseJack attacks that affected Unifying receivers by leveraging BLE's built-in encryption and secure connection standards. Both technologies support pairing up to six compatible devices per receiver and offer a reliable operating range of approximately 10 meters, but Logi Bolt extends functionality with seamless multi-computer flow capabilities—enabled through Logitech's Flow software—allowing users to control multiple systems without perceptible lag or the need for repeated re-pairing. Newer Logitech devices may use Logi Bolt instead, which is incompatible with Unifying receivers. Devices compatible with the Unifying receiver, introduced in 2009, cannot pair with Logi Bolt receivers due to fundamental protocol incompatibilities, necessitating separate ecosystems for each technology and preventing cross-use within the same setup.

Current Status and Alternatives

As of November 2025, the Unifying receiver continues to be produced and sold through official channels, with the hardware remaining compatible with a range of legacy Logitech wireless peripherals. Functionality for device pairing and management is now provided through Logitech's Logi Options+ software (the older Unifying Software is deprecated), which supports Unifying receivers and receives regular updates across Windows, macOS, and systems. Despite its persistence in existing setups, the Unifying receiver lacks a native connector, necessitating the use of adapters like Logitech's official USB-A to dongle for integration with modern laptops and devices featuring ports exclusively. It remains prevalent among users maintaining older hardware configurations, where its ability to connect up to six devices via a single 2.4 GHz USB receiver provides a reliable, low-latency solution without relying on built-in wireless options. Contemporary alternatives to the Unifying receiver include native (BLE) pairing supported directly by operating systems such as and , which enables seamless connectivity for devices with integrated . For enhanced security and performance in professional environments, 's Logi Bolt receiver serves as a direct upgrade, offering encrypted 2.4 GHz connections compatible with newer peripherals. Looking forward, is prioritizing Logi Bolt and technologies in its product roadmap, while sustaining Unifying receiver support to accommodate legacy compatibility needs.
