Debian Hardware :: Unable To Disable Mouse Acceleration

I'm using Debian Jessie with nvidia, and i am unable to disable mouse acceleration.

I have tried using this config in xorg.conf.d but without success.

Code:
Select all Section "InputClass"
   Identifier "Cooler Master Storm Havoc Mouse"
   MatchIsPointer "yes"
   Option "AccelerationProfile" "-1"
   Option "AccelerationScheme" "none"
EndSection

In the xorg log it seems as if the devices are incorrectly recognized

Code:
Select all[     6.786] (II) config/udev: Adding input device Cooler Master Storm Havoc Mouse (/dev/input/event9)
[     6.786] (**) Cooler Master Storm Havoc Mouse: Applying InputClass "evdev keyboard catchall"
[     6.786] (II) Using input driver 'evdev' for 'Cooler Master Storm Havoc Mouse'
[     6.786] (**) Cooler Master Storm Havoc Mouse: always reports core events
[     6.786] (**) evdev: Cooler Master Storm Havoc Mouse: Device: "/dev/input/event9"
[     6.786] (--) evdev: Cooler Master Storm Havoc Mouse: Vendor 0x2516 Product 0x1d
[     6.786] (--) evdev: Cooler Master Storm Havoc Mouse: Found 1 mouse buttons

[Code] ....

Here it seems as if the mouse is recognized twice, once as a mouse and once as a keyboard, where it says "Cooler Master Storm Havoc Mouse: (accel) keeping acceleration scheme 1" so I'm wondering if this is what causing the problem with mouse acceleration not working.

However my USB headset also seems to be recognized as a keyboard in the xorg log, but it works just fine. In xinput list and xfce mouse settings, the mouse is listed twice and even the keyboard is listed as a mouse.

Code:
Select allVirtual core pointer                       id=2   [master pointer  (3)]
⎜   ↳ Virtual core XTEST pointer                 id=4   [slave  pointer  (2)]
⎜   ↳ Cooler Master Storm Havoc Mouse            id=9   [slave  pointer  (2)]
⎜   ↳ Cooler Master Storm Havoc Mouse            id=10   [slave  pointer  (2)]
⎜   ↳ Logitech USB Keyboard                      id=11   [slave  pointer  (2)]
⎣ Virtual core keyboard                      id=3   [master keyboard (2)]

[Code] ....

in dmesg, the mouse is also listed twice, once as a mouse and once as a keyboard
