Well, I try the evtest.c program under kernel 2.4.0. I use the following line 
to compile it:

gcc -O2 -Wall -I/usr/src/linux/include evtest.c -o evtest

assuming that /usr/src/linux is a link to /usr/src/linux-2.4.0.SuSE/

When I run it, evtest gives me bad numbers (soft, prod, vendor numbers...), 
enters in an infinite loop telling me "yyy" (!?) and when I mouve the mouse, 
exits the loop and display and error message (Ioctl()...). Evtest displays 
this:

===
Input driver version is 16.144.0
Input device ID: bus 0x0 vendor 0x0 product 0x5 version 0x0
Input device name: "Unknown"
Supported events:
Testing ... (interrupt to exit)
yyy
 
evtest: error reading: Ioctl() inappropr? pour un p?riph?riques
===

I think that this come from a bad compilation of evtest...
Perhpas the good choice is to install a newer kernel but I've just got the 
SuSE 7.1 ?

The /dev/input/eventX seems to be appealing, so any help should be 
appreciate. Obvulsy, I can't find many document about its usage...

Is there a simple way to make this change ? 


Thanks,
