How to set per-device mouse sensitivity : Revisited !

Hi,

Again, I hit in the whizzingly fast mouse problem with Xorg. With my
previous release of Xorg (1.7.6) I solved this using a hal FDI file.
Here is the link fore reference :

http://www.gossamer-threads.com/lists/gentoo/desktop/207830

The solution was to merge this XML fragment in HAL :

<?xml version="1.0" encoding="ISO-8859-1"?>
<deviceinfo version="0.2">
<device>
<match key="info.product" contains="Bluetooth Laser Travel Mouse">
<merge key="input.x11_options.ConstantDeceleration" type="string">2</merge>
<merge key="input.x11_options.AccelerationProfile" type="string">-1</merge>
</match>
</device>
</deviceinfo>

in order to set the options ConstantDeceleration and
AccelerationProfile to sane values.

Today I tried Xorg 1.8.0, and I added this content to
/etc/X11/xorg.conf.d/10-evdev.conf :

Section "InputClass"
        Identifier "My mouse"
        MatchProduct "Bluetooth Laser Travel Mouse"
        Option "AccelerationProfile" "-1"
        Option "ConstantDeceleration" "10"
EndSection

In Xorg log (Xorg -retro -verbose 10 2>log) I see :

(II) config/udev: Adding input device Bluetooth Laser Travel Mouse
(/dev/input/event12)
(**) Bluetooth Laser Travel Mouse: Applying InputClass "My mouse"
                 <<<<<<<<<<<
(**) Bluetooth Laser Travel Mouse: Applying InputClass "evdev pointer catchall"
(**) Bluetooth Laser Travel Mouse: always reports core events
(**) Bluetooth Laser Travel Mouse: Device: "/dev/input/event12"
(II) Bluetooth Laser Travel Mouse: Found 12 mouse buttons
(II) Bluetooth Laser Travel Mouse: Found scroll wheel(s)
(II) Bluetooth Laser Travel Mouse: Found relative axes
(II) Bluetooth Laser Travel Mouse: Found x and y relative axes
(II) Bluetooth Laser Travel Mouse: Configuring as mouse
(**) Bluetooth Laser Travel Mouse: YAxisMapping: buttons 4 and 5
(**) Bluetooth Laser Travel Mouse: EmulateWheelButton: 4,
EmulateWheelInertia: 10, EmulateWheelTimeout: 200
(II) XINPUT: Adding extended input device "Bluetooth Laser Travel
Mouse" (type: MOUSE)
(II) Bluetooth Laser Travel Mouse: initialized for relative axes.
(II) config/udev: Adding input device Bluetooth Laser Travel Mouse
(/dev/input/mouse2)
(**) Bluetooth Laser Travel Mouse: Applying InputClass "My mouse"
(EE) No input driver/identifier specified (ignoring)

So I assume my options are merged in the configuration. But it has no
effect. What can be wrong ?
