Mouse reduced to a three button mouse when unpluged/repluged

Question

It's me and my mouse again.
This time the problem is that the scroll and side buttons stops working when I unplug and erplug the mouse back in again. It's a Logitech MX518 mouse.
My MX518 use /dev/input/event4.
# cat /proc/bus/input/devices
I: Bus=0003 Vendor=046d Product=c01e Version=2200
N: Name="Logitech USB-PS/2 Optical Mouse"
P: Phys=usb-0000:00:1d.1-2/input0
S: Sysfs=/class/input/input4
H: Handlers=mouse2 event4
B: EV=7
B: KEY=ff0000 0 0 0 0 0 0 0 0
B: REL=103
This is a part of my /etc/X11/xorg,conf
Section "Inputdevice"
# Logitech MX 510/518
Identifier "EvdevMouse"
Driver "evdev"
Option "Device" "/dev/input/event4"
EndSection
Section "Inputdevice"
# IBM Thinkpad Touchpad
Identifier "Mouse2"
Driver "mouse"
Option "Protocol" "auto"
Option "Device" "/dev/psaux"

Section "ServerLayout"
# The Identifier line must be present
Identifier "Laptop"
Screen "Laptop single"
Inputdevice "EvdevMouse" "CorePointer" # Mouse
InputDevice "Mouse2" "SendCoreEvents" # Touchpad
InputDevice "Keyboard1" "CoreKeyboard"
EndSection
When I unplug my mouse, the /dev/input/event4 is removed. When I replug my mouse back in again, a new event is created named /dev/input/event5. And my mouse is suddently reduced to a three button mouse. To fix this, I have to kill X, unplug/replug my mouse, and start X again.
This is after unplug/replug the mouse without restarting X

Have tried to create a udev rule, without any luck.
ACTION=="add",
KERNEL=="event*",
SUBSYSTEM=="input",
SYSFS(manufacturer)=="Logitech",
SYSFS(product)=="USB Receiver",
NAME="input/mx518"
Does anyone have an idea that can be done to fix this.

I'm using udev to create links for my Logitech MX700 Duo (Logitech Elite keyboard + MX700 mouse).
Here are my udev rules:
# Laptop keyboard
BUS=="serio", SYSFS{description}=="i8042 Kbd Port", SYMLINK+="input/clavier"
# Alps TouchPad
# GlidePoint
BUS=="serio", SYSFS{description}=="i8042 Aux Port", KERNEL=="event?", SYMLINK+="input/touchpad"
# StickPointer
SUBSYSTEM=="input", SYSFS{dev}=="13:32", SYMLINK+="input/stick"
# MX700 Duo
# Keyboard
BUS=="usb", SYSFS{bInterfaceNumber}=="00", SYSFS{bInterfaceProtocol}=="01", NAME="input/%k", SYMLINK+="input/mx700duo_clavier"
# Mouse
BUS=="usb", SYSFS{bInterfaceNumber}=="01", SYSFS{bInterfaceProtocol}=="02", NAME="input/%k", SYMLINK+="input/mx700duo_souris"
The bInterfaceNumber/Protocol are the only thing that can differcienciate the two (same wireless receiver...).
Hope you will be able to adapt it to your kb/mouse.
I've never been able to make work 100% of it. Since the symlinks disapear if I unplug the usb mouse/kb, I can't unplug and replug them if Xorg is running...
I would like to be able to control each of the devices independantly, like this:

If the last line is uncommented, X doesn't work... I really don't know why. And now that Xorg 7 is installed, my mouse is 32 buttons!!!! This is a nightmare...
