I bought this mouse, logitech m510, which came with a nano receiver (no-unifying).
Yes I know, the mouse is supposed to come with a unifying receiver but I bought it knowing that it won't come on it's original package and it will come with a no-unifying receiver.
When I received it, everything worked ok but, after connecting the mouse to another computer using an unifying receiver (that also worked ok, btw), then, when I tried to connect back the mouse to my computer using the no-unifying receiver, I couldn't connect it.
I tried everything from removing the batteries and reinstalling the drivers to restarting the computer and trying in different computers, but I couldn't connect them.
What I think it happened, is that in fact if you check the documentation of the logitech m510 it says that it works with unifying receivers only, and even more, there is the following article explaining it: http://logitech-en-amr.custhelp.com/app/answers/detail/a_id/18001/~/using-my-m510-with-a-different-usb-receiver
So my theory is that the problem was connecting it to a unifying receiver, and now, isn't recognize by another receiver.
The receiver (the no-unifying one) itself is recognized by windows, and if I connect the mouse using a unifying receiver, it works.
I would like to know if there is any know solution for this or if I can try something else to see if I can solve this.

At the end, after asking the seller for a solution to my problem, he sent me the following link: http://support.logitech.com/software/logitech-connection-utility-software
It's the software Logitech Connection Utility, copy pasted from the link I put above: "It can be used to reconnect supported keyboards or mice with a replacement receiver or when the connection is lost."
It solved instantly the problem I described in my question.
