Logitech USB Unifying Receiver - Black

Using this, and an old Logitech software app, I was able to pair my keyboard and mouse to two receivers and switch between them using the 1,2 buttons. Effectively removing the need for a KVM switch in my setup.

Sucessfully paired this with an old 2011 M505 laser mouse. I'd seen USB errors on the laptop (device not taking address) and thought it was the laptop that was at fault. On trying the old receiver in another machine, saw the same errors. So ordered this later version of the receiver.The M505 mouse is not specifically listed anywhere as compatible. But it works fine.Simple to pair the new receiver with the old mouse on a linux host with ltunify: `ltunify pair`. Turn on the mouse. `ltunify list`. All done.

Essential for a wireless mouse

This Logitech USB Unifying Receiver performs great with devices that support it. However, be sure to check compatibility before buying—it’s not compatible with the K380 keyboard. If your devices are on board, it’s a reliable choice!

won't pair, you have to download software before you can use the usb receiver, pointless if you can't connect your mouse or keyboard to download !!!!

Works for my K400 plus keyboard, but had to download the Unifying Software as someone mentioned in a previous review.

Was using a mx key and Mx anywhere mouse. Logitech told me there was a firmware update but wouldn't work with Bluetooth. I bought this to complete the update.The update suddenly was not there. Thanks logitech! Also it wouldn't connect to the keyboard either. A bit rubbish

I bought this for use with an MX Master 3 mouse on a Windows 10 computer, however, despite setting itself up when I plugged it in the first time there appeared to be a driver issue.This can be seen in Settings>Devices with a message such as "Driver is Unavailable" or "Driver Error" as seen in the image (side note, my mouse was connected to my devices Bluetooth when the picture was taken, not to the receiver).To resolve the driver issue follow the below steps and install all 3 softwares from Logitech's official website.1. Install Logitech Options software (allows you to customise your devices settings)2. Install Logitech Unifying software (does the actual pairing)3. Install Logitech SetPoint software (is for some reason required to make everything work, might just come with the necessary driver for the receiver)4. Open Logitech Options5. Click add device6. You should have 3 choices select add a Unifying device7. It should open the Unifying receiver app in a new window, follow the on-screen instructions to pair your device.8. You're done, your mouse/keyboard is now paired with the receiver, you can also plug that receiver into other computers without the need to install those softwares or re-pair your mouse/keyboard to the receiver.Hope this helps.
