Extras buttons of Microsoft Comfort Optical Mouse 3000 doesn't work.

Changing xorg.conf InputDevice section to this, the back button worked fine (in firefox):

Section "InputDevice"
    Identifier "Configured Mouse"
    Driver "mouse"
    Option "CorePointer"
    Option "Device" "/dev/input/mice"
    Option "Protocol" "ExplorerPS/2"
    Option "Emulate3Buttons" "no"
    Option "ZAxisMapping" "4 5"
    Option "Buttons" "8"
    Option "ButtonMapping" "1 2 3 8 6 7"
EndSection

Now, only the horizontal scroll don't work.

Thank you for your bug report. Do you still have this issue with the latest release of Ubuntu ?

Since Warty nothing has changed...

Ok, I'm marking this as confirmed.

Hello,
I'm using this mouse on Ubuntu Hardy.
With the configuration proposed by Guilherme Paula the mouse simply don't work.
I have to use backup xorg.conf to make it work again.
The backup configuration (that work like a 2button+wheel) is:

Section "InputDevice"
 Identifier "Configured Mouse"
 Driver "mouse"
 Option "CorePointer"
 Option "Device" "/dev/input/mice"
 Option "Protocol" "ExplorerPS/2"
 Option "ZAxisMapping" "4 5"
 Option "Emulate3Buttons" "true"
 Option "Buttons" "8"
 Option "ButtonMapping" "1 2 3 8 6 7"
EndSection

PS: sorry for my english

But this is the configuration I had suggested...

What's wrong after you put this configs ?

D'oh!

Obviously you're right, it's your configuration working (I made mistake with other configuration I tried).
Anyway, the red button on the side doesn't work.
Changinh Compiz settings, I found that the side button is "button 9". I don't understand wich are button 6, 7 and 8, but the 9 is side button, and if I set it for an action it work.
Can you suggest me how to change the configuration?
Thank you very much

The red button only work here in Firefox with the "Back" function.
About the others buttons, i think they are like this:

1- Left Click
2- Right Click
3- Scroll Click
4- Scroll up
5- Scroll down
6- Scroll left
7- Scroll right
8- I don't know :-(
9- Red Click (Original Zoom function by Microsoft)

Using command "xev" in a terminal I found:

1 - left click
2 - scroll click
3 - right click
4 - scroll up
5 - scroll down
6 - nothing
7 - nothing
8 - nothing
9 - red click

How can I change my xorg.conf "InputDevice" section to use these button?

If you are using the configuration I've wrote, I think you are already using these buttons.
As I can see, only remains know how to enable the horizontal scroll (yes, the mouse has this function).
If you find how to use then, please leave a messenge here.
Thanks

I tried the change to /etc/X11/xorg.conf described above, but the changes did not work and the buttons remained inactive. However, I continued to research the problem and I was able to find a solution that worked for me. First, thanks to Ubuntu community docs, I reconfigured the Optical Mouse 3000 buttons like described in the Dell 7 button mouse configuration at https://help.ubuntu.com/community/ManyButtonsMouseHowto. I did this by creating the 57xmodmap in /etc/X11/Xsession.d (see attached). Then I changed the relevant section in my /etc/X11/xorg.conf file to the following:

Section "InputDevice"
    Identifier "Configured Mouse"
    Driver "mouse"
    Option "CorePointer"
    Option "Device" "/dev/input/mice"
    Option "Protocol" "auto"
    Option "Buttons" "9"
    Option "ZAxisMapping" "4 5"
    Option "ButtonMapping" "1 2 3 7 6"
EndSection

Now the back function works just fine on my mouse. Took almost 2 hours to solve the problem, but thanks to the Ubuntu Community docs and previous posters on launchpad, I was able to come up with a solution. Hope my config works for you. As alwasys, please make backups of any config files you change, could save you problems later.

Ubuntu Hardy Heron 8.04
Firefox 3.0 RC1

I have a MS Comfort Optical Mouse 3000. After a fresh install of Ubuntu 8.04.1, I find the back button (red button on the side) doesn't work in FireFox. I followed vaporstx's instructions. It finally works. Thanks.
