what to do with my spare unifying receiver
Logitech Unifying receiver (Older)
Logitech Unifying receiver (Newer)
The Logitech Unifying receiver is a small-scale dedicated USB wireless receiver, based on the nRF24L-family of RF devices,[1] that allows upwards to six compatible Logitech homo interface devices (such as mice, trackballs, touchpads, and keyboards; headphones are not compatible) to be linked to the same computer using 2.4 GHz ring radio communication. Receivers that are bundled with a Logitech product are paired with the device at the manufactory. When purchasing a replacement receiver or connecting multiple devices to one receiver, pairing requires the costless-of-accuse Logitech Unifying software, available for Microsoft Windows and Mac OS 10. Although non compatible with Bluetooth, devices pair to Unifying Receivers in a like style.[2] Peripherals remain paired, and can then be used on systems non supporting the software. Logitech receivers compatible with the Unifying protocol tin can be identified past the orange Unifying logo, which distinguishes them from Logitech Nano receivers of similar advent, which pair in a similar mode but only with a unmarried 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 permit a receiver to be stored within.[3]
Every bit of October 2019[update] Logitech Unifying Software for Windows had last been updated, to version 2.fifty.25, on 30 March 2010.[4]
Compatibility and use [edit]
Each peripheral device can pair to one receiver per profile. While most peripherals only shop one profile, newer products such equally the Logitech MX Master, MX Anywhere serial, and M720 Triathlon allow multiple profiles. These devices can be continued to multiple receivers simultaneously. This allows the use of receivers in several computers, e.g., a desktop and a laptop estimator, selecting the computer to employ by changing profiles on the mouse. This multi-calculator function is further augmented by Logitech Menstruum (software KVM solution) which is like to Synergy. For devices without multi-computer support, the receiver and input devices can be moved together from ane computer to another, maintaining their paired status after existence unplugged, every bit the pairing information is held in the petty 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 too allows the use of peripherals on computing devices that do not back up Unifying Software, e.1000. devices supporting USB OTG with operating systems such equally Android: first pair to the receiver on a PC or Mac.[v]
Some older Unifying devices limit the number of allowable pairing changes to a maximum of 45 times. Once the 45th connexion is made, information technology is no longer possible to connect such a device to a different receiver. For users who oftentimes switch a Unifying device between multiple PCs or laptops with individual receivers, this connexion limit tin become an issue. For case, a user who often switches a mouse between two receivers (e.grand. at work and domicile) will apace exhaust the limit of available pairing switches.[half-dozen] Logitech advises customers with this result to contact their Client Intendance. 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.two.[vii] Software to manage Unifying devices on Linux is available from third party developers, such as Solaar.[8]
Many companies accept fabricated 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 apply, 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 have been reported in 2016 and 2019,[9] and patches released.
MouseJacking and keyjacking [edit]
MouseJacking, offset reported past 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 nearly 100 meters. Possible exploits include:
- Keystroke injection by either spoofing a paired mouse or keyboard
- Forced pairing

Response [edit]
Logitech has released Unifying receiver firmware updates as new exploits were reported.[15] [xvi]
Linux users can use fwupd to flash an updated firmware. Information technology will automatically detect bachelor updates for any connected unifying receivers and many other firmware updatable devices. An outdated alternative is MouseJack.[1]
Flashing on a Linux/UNIX host via a hypervisor such equally VirtualBox along with a Windows virtual invitee image and the Windows Logitech update executable is also possible. If using a Windows virtual guest, information technology is recommended to accept a second bachelor pointing device while the dongle is being updated. The 2nd pointing device may be needed to allow the user to select and enable laissez passer through of the unifying receiver via the hypervisor chore bar later on 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 past a dissimilar researcher.[nine] 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 existence sold that were vulnerable to the original 2016 MouseJacking assail.[17]
