Elantech touchpad detected as Logitech PS2 Wheel Mouse

[Nicola Alessi <nialessi@gmx.com>]

Hi,

I'm running debian wheezy with latest kernel (uname -a gives me: Linux
ehehehpc 3.2.0-2-686-pae #1 SMP Sun May 13 07:51:23 UTC 2012 i686
GNU/Linux).
While I'm expecting the kernel to correctly detect my touchpad, it's
detected as a mouse. No scrolling, no multitouch.
Below there's a snippet of my /proc/bus/input/devices:

[...]
I: Bus=0011 Vendor=0002 Product=0001 Version=0063
N: Name="PS/2 Logitech Wheel Mouse"
P: Phys=isa0060/serio4/input0
S: Sysfs=/devices/platform/i8042/serio4/input/input7
U: Uniq=
H: Handlers=mouse0 event7
B: PROP=0
B: EV=7
B: KEY=70000 0 0 0 0 0 0 0 0
B: REL=103
[...]

The notebook I'm using is a Fujitsu Siemens Amilo pi2515.
I also tried kernel version 3.3.6 with same results.
In both cases grep ELANTECH .config gives me:

CONFIG_MOUSE_PS2_ELANTECH=y

so I suppose it shouldn't be a kernel configuration problem.
I opened a bug on http://bugs.debian.org/673588
You can find more information and preliminary testing there.
Thank you very much for your attention.
Regards.
