Question about Logitech M505 Wireless Mouse Red

Unifying receiver not recognizing M505 Wireless Mouse

My mouse abruptly stopped working today. It still turns on (the light on it turns on and is not blinking in any suspicious fashion) and the computer still acknowledges the unifying receiver, but the receiver believes the mouse to be inactive and absolutely will not detect it no matter what I try. On that note, I have tried... - Changing the batteries - turning it off and on. - restarting my computer. - installing the software off of Logitech's website (which is how I know the problem this specifically). - attempting to use it on my roommate's computer (again, the receiver's driver was installed, but it could not detect the mouse) - updating drivers (they are as up-to-date as possible) - switching the receiver into different ports. - cursing the names of various deities. I have had no luck. Am I overlooking something? This mouse is only a few months old, and I bought it because my roommate has the same model and it has done well for him. I really need this mouse to work and I can't afford a new one at this point...

    After looking at it a little more closely, the light on the mouse is red (apparently it's supposed to be green sometimes? I must admit, I only tend to pay attention to the thing when I think something might be wrong >__<). Now, it's pulsing red almost constantly, with occasional brief blinks, whereas my roommates still-functioning mouse will light up for a moment after being turned on, but then darken afterward (and function normally the entire time).

    Here's another update! On a whim, I tried fully shutting my computer off. Figured I may as well see what that does. Just in the final moment before it went to the shut down screen, I heard the tone it plays when something is taken out of a usb drive. I tried moving the mouse and to my surprise, it worked! A while later, I turned my computer back on, and the mouse functioned as normal! The light was on only briefly at start-up, and the cursor moved just fine and everything! This lasted until I tried opening the Logitech mouse utility and just as I was texting my roommate about how the mouse had mysteriously started to work again... then it started malfunctioning in the exact same way again... near-constant light, no cursor movement. The program still doesn't detect the mouse ever. I tried shutting down again, but this time nothing changed. Even with the machine off, the mouse light still kept on shining. What the hell is going on here?

    And... not a minute after I post that last message, it starts working again. Needless to say, I am befuddled. I think you, problem-solvers of the internet, may as well assume this is going to keep doing this intermittently.

    and three minutes later, it's off again. Yeah. -_-"

It could be that the mouse that you are trying to connect is already paired with another active Unifying Receiver. When the mouse is turned on it will pair itself with this other PC rather than register as a new device.
Is there another computer nearby which has already been paired with the mouse? (I had 2 laptops one of which was in Sleep/Hibernate mode and I had to deregister the mouse from that one before I could reconnect)

You mentioned about using the mouse in your friend's computer but you didn't mention if it worked or not. Did it work?
You also mentioned that your friend has the same model which works perfect with his computer. Did you try his mouse in your computer? Did it work?
If his mouse works just fine in your computer then you would need to replace your mouse because it's defective.

If it is a USB wireless then your operating system will not need any additional drivers. The USB port takes care of that. Windows XP and Vista support almost 100% of any USB wireless mouse including Logitech..I own three of them, never had a problem. The only problem would be the USB port itself. Which is a totally different subject. You can still also go into control panel and make mouse adjustments if needed.

Please rate solution.

Search the web for a receiver for your mouse is about all I can suggest. You might want to start with E-bay or other auction sites. Best of luck on this quest.

SOURCE: My Logitech EX 100 keyboard and mouse combo doesn't work

Make sure the batteries work by testing them in another device(sometimes they lose their charge if they have been in the box too long). If they are charged, make sure you have the devices connected directly to the computers onboard USB port so that you can be sure it is getting enough power to the reciever.

If this does not work, it might be a hardware setting on windows. You will want to make sure all of your drivers are installed properly in device manager, this is unlikly the problem but it has been known to happen. Make sure the mouse and keyboard are aligned properly with the reciever.

If your computer is running slow, it may just take a long time for windows to recognize the new device. If you do not hear windows responding by making the 'new device found' sound then it probably is not detecting the new device in which case it is probably something wrong with windows or the drivers. If it does make the sound and it says it is loading and you see the ballons pop up on the bottom right then it has sucessfully connected.

If all of this does not work, then I would say that they are toast. Try them on a different computer if you can. This should give you a definate idea of if it is a problem with your computer or a problem with the device itself.

SOURCE: The mouse does not work

Change the batteries. If still a problem, try the mouse on another workstation. If it still doesn't work, it will confirm that the mouse or USB receiver is faulty.

If i do not get any usb reciever of wireless mouse then can i buy it from an other company


If it's a bluetooth mouse or a logitech unifying mouse then you can find a receiver elsewhere (not sure if the unifying receiver is ever sold separately). Other than that the wireless stick for each mouse is pre-paired with that mouse and I don't think you can get replacements even from the manufacturer.

What does the device manager say about the hardware?
It could be loss of the usb device controller. Windows XP is old and that is an indication that the hardware is old too.

Try resyncing the mouse, especially if you just replaced the batteries. Press the sync button on the receiver and then the one on the bottom of the mouse.

Microsoft wireless mouse 3000 - all lights are on; flash upon reset, but still doesn't work. Running Vista 64-bit.


Try to take off battery and next push and hold down the small button that protrudes where the receiver is placed in the mouse, put back battery and simultaneusly release the button,it might make the mouse operate correctly. Good luck!!!! Chawah.

Now what you have to do is look for a reset button on your mouse and your wireless mouse signal receiver.
When the receiver and mouse both are on press the reset button on both of them one by one.
This should solve the problem.
