Logitech keyboard and mouse selections for PC and accessories
Okay, boys and girls. It's time to play the Match Game. As I previously mentioned, I have two wireless keyboards ans one wireless mouse. I also have three non-unifying dongles and three unifying dongles. So which will work with which? The * signifies unifying dongle.

What are you inquiring about?
Test each option.
Connect the first dongle.
Link it to the mouse. Works?
Link it to the keyboard #1. Works?
Link it to the keyboard #2. Works?
Continue with the next dongle.
Tried it before, KB & Mouse functioned briefly but later became faulty.
I wouldn't assume the issue is specifically Windows 11.
I'm using Windows 11 (Pro) with two systems and Logitech setups.
I don't rely on any unifying software.

If keyboards or mice aren't functioning, check Reliability History/Monitor and Event Viewer for any Logitech, keyboard, or mouse-related error codes, warnings, or notes.
Device Manager also logs device-related events.
Execute "dism" and "sfc /scannow" – Windows may detect and resolve some related bugs or corrupted files.
Ensure you have the proper drivers installed. Download directly from Logitech – avoid third-party tools or installers.
I tested a K270, a K540 and a k350 keyboard with my Win11 system. I used various unifying and standard USB dongles. None of the keyboards connected to the computer. My Windows 11 version is up to date as of August 19, 2025. Why are they not pairing? Is this another case where Mictosoft's representatives intentionally disabled their products that previously worked well under a different operating system, forcing users to purchase new equipment like they did with Windows 10? All three keyboards I tried?
Just got to mention that the orange dongles paired with the * make using Unify software incredibly straightforward. For multi-device wireless keyboards and mice, Logitech seems to be the top choice in my opinion. You can buy only the receiver or USB side of these devices and get familiar with them quickly. Very simple and easy. I expect they will still fail at a similar rate over time compared to cheaper USB WiFi dongles, so keep that in mind. I always have an extra one available.
