![]() Once the 45th connection is made, it is no longer possible to connect such a device to a different receiver. Some older Unifying devices limit the number of allowable pairing changes to a maximum of 45 times. devices supporting USB OTG with operating systems such as Android: first pair to the receiver on a PC or Mac. This also allows the use of peripherals on computing devices that do not support Unifying Software, e.g. ![]() 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 -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 multi-computer function is further augmented by Logitech Flow (software KVM solution) which is similar to Synergy. 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. These devices can be connected to multiple receivers simultaneously. While most peripherals only store one profile, newer products such as the Logitech MX Master, MX Anywhere series, and M720 Triathlon allow multiple profiles. Compatibility and use Įach peripheral device can pair to one receiver per profile. Some Logitech peripherals allow a receiver to be stored inside. Logitech Unifying receivers (LURs) are often included in wireless Logitech keyboard, mouse, and combo sets, and may be purchased separately. 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. Peripherals remain paired, and can then be used on systems not supporting the software. Although not compatible with Bluetooth, devices pair to Unifying Receivers in a similar way. On Linux the Solaar software can be used to adjust the configurations. 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. Receivers that are bundled with a Logitech product are paired with the device at the factory. Seriously, Logitech, if you can't write a driver that continues to function for more than three days at a time, you should outsource to somebody who can.The Logitech Unifying receiver is a small dedicated USB wireless receiver, based on the nRF24L-family of RF devices, 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. This is with a clean install on two different OSes over a period of months. It has reduced a fantastic piece of hardware to something that is maddeningly unpredictable. Only solution is to log out and back in.Ĭalling this frustrating is putting it mildly. Force quitting the process won't fix it, either. Open the Options, and everything is configured right, the driver has just decided to completely ignore your configuration. Suddenly scrolling will stop working until I turn it off and back on, or the back button will start doing the equivalent of option-click, or the Expose buttons will stop doing anything at all. Sometimes as often as once a day, and always within a week, the mouse will just start ignoring all Logitech configuration. except it is absolute garbage when it comes to stability, which is what really counts. Support? Regularly updated and actually supported 10.14 on day one! Interface? Beautiful and has a mix of ease of use and advanced features buried one level deep. ![]() ![]() Features? Fantastic! It's incredibly customizable and has cool extras like Flow. But you know what? When they eventually got around to it, at least it usually worked correctly. I used to lament Logitech Control Center because it was crusty-looking and took weeks or months to be updated to support new products or OSes.
