The Logitech RX300 mouse wheel have two extra clicks (side left and side right)

this mouse. Tested with the different drivers (mouse, evdev...) and the
different protocols (ImPS/2, Explore/PS2...)

The 'xmodmap -pp' output is:

There are 5 pointer buttons defined.

The 'cat /proc/bus/input/devices' output for the mouse is:

All the other functions of the mouse (3 standar buttons plus wheel) work
well.
