Can't Pair device Unifying Software

Hi there,

I have a M325 mice, I use it at home and at work, with my keyboards K360 (both at home and at work).

What I do is I do not carry the usb device with me, I have 1 unifying usb receiver connected to my home workstation and 1 unifying usb receiver connected to my work workstation. So when I go work I carry my mouse with me and pair it at work, and at night take my mouse back with me and pair it with the home workstation. Last week suddenly it just stopped pairing, and a warning comes up when I try to pair it via unifying software.

New battery, tried different computers, etc, nothing worked.

I read something about a limit of 45 attempts somewhere in the website, this sure can't be true though or is it?,

If yes, what am I going to do now?

If no, then what can be the cause of the problem?

Re: Can't Pair device Unifying Software

Hello Muty, 


As you can see on this FAQ, there is a pairing limitation for some Unifying devices. There's a chance that you can no longer pair your M325 with the receiver in your house because it has reached the limit.


If the receiver at your work is the last one the mouse was paired to, it should still work, and it could still be re-paired to that receiver. I would recommend that you take that receiver along with your mouse, so you can use it at home and at work. There's a space inside the mouse's battery compartment where you store the receiver, so it won't get lost.


I hope that you find this information useful Muty, let me know if you have further questions.
