I am new to this site.

My problem is with the M205 USB wireless mouse.  My computer doesn't recognize the mouse.  The green light comes on when you put the battery in. I never see a laser on bottom of mouse.  The moue is on and I press the connect button and I get nothing.  I have 4 USB ports and it will not work in any of them.  This is the second one I have bought and both have not worked.

Re: M205

Try running the Unifying software util to reconnect the receiver and mouse.

Re: M205

I have an M205 mouse and it was working early today and now it has stopped very similar to how the first post is mentioning. due to my own personal carelessness. I cannot find my software that came with the mouse.. is there anything on this website that can get this mouse to work.

I actually have the same problem with my M205. It worked perfectly until a windows update, now it doesn't work at all, even went through the pain staking process of formatting and reinstalling the OS (win7), still doesn't work. the unifying program doesn't recognize it either.

Re: M205

Hello All:


Thank you for expressing concerns with your M205. For the great majority of you you seem to not have any connectivity between your mouse and receiver.


As noticed, I have included 2 links in regards to setpoint. Please install the appropriate version of setpoint whether your computer has a 32 or 64 bit Operating System.

32 bit:

64 bit:


Afterward please go to:

Start->All Programs-> scroll to Logitech->Unifying->Logitech Unifying Software


Please follow the instructions with the receiver plugged in. You may have to run this program a couple times to get the desired affect


If running the unifying software does not work please put your computer into a cleanboot mode and try running the unifying software from there. (see below),-vista,...


Other troubleshooting steps you can try are:


-does this device work on another computer

-in Device Manager is the mouse even showing up(enumerating) under Mice and Other pointing Devices


As for byebye009, if you go to: Start->Control Panel->Mouse->under button in the third section , is ClickLock checked or unchecked. If so then uncheck. If not then:

-try running in a cleanboot mode(see above)

-does it work on another computer

Download M305 connection utility. I just tried to install this mouse with the same problems everyone mentioned.


I downloaded the utility and it worked immediately when I followed the prompts.
