Hi, ppl. I'm trying to learn to develop modules for some hardware,
but now I'm learning from an example. First need to know which module
in /proc/modules runs mouse or keyboard.
How to find this out? Simple command like lsmod or cat /proc/modules
didn't say that. How to find our relation between a loaded module and
it's source code?

Something to start with ......

... And by the way : The driver used in X isn't a kernel module.
