Hi,

as I can see from https://bugs.launchpad.net/ubuntu/+bug/365435 it's
subject is: "xbox 360 wireless controller acts like curser or mouse."

But xpad.c doesn't use any relative axes. What it used were mouse
buttons, but this was fixed with following commit:

    Input: xpad - remove mouse buttons and axes for dance pads
    
    Dance pads don't have any axes/sticks, only buttons for directions. For
    example buttons like left+right will get triggered at once, an axis
    can't handle this anyway.  So this patch adds a module parameter named
    "sticks_to_null" for unknown devices. A known dance pad makes use of
    it by changing to a new mapping-option named DANCEPAD_MAP_CONFIG. Other
    tested devices may follow by adding this mapping-option too.
    
    Some buttons of xpad-devices are addressing mouse-buttons instead of
    gamepad-buttons. This gets fixed too.
    

And maybe we should make module param dpad_to_buttons work for known
pads too, so that a user can decide if the pressure should get measured
in simple key_events (0 or 1) or as an axis with "analog" values.
Because all programs (games) I know of don't like buttons reported as
axes. Even further, I was told that most xbox games don't make use of
this pressure-hitting-button-feature.
So if it would be up to me - I would remove the whole analog-button
thing or make option dpad_to_buttons default. Should I go for it?

 thanks,
