Event debugging

modulename: evbug.ko

configname: CONFIG_INPUT_EVBUG

Linux Kernel Configuration
└─>Device Drivers
└─>Input device support
└─>Event debugging
In linux kernel since version 2.6.20 (release Date: 2007-02-04)  
Say Y here if you have a problem with the input subsystem and
want all events (keypresses, mouse movements), to be output to
the system log. While this is useful for debugging, it's also
a security threat - your keypresses include your passwords, of
course.

If unsure, say N.

To compile this driver as a module, choose M here: the
module will be called evbug.
