Any software/hardware hack to adjust deadzones on Generic USB Joystick/Gamepad analog sticks?

[qrime]

this is exactly what the controller look like - http://postimg.org/image/lbyhh12yj/

The gamepad uses axial deadzones which results in unsmooth and snappy movement when rotating the sticks around 360 degrees (the actual sticks can be moved 360 degrees however in games it is not smooth and the deadzones are fairly noticeable).

I tried using x360ce, Xpadder, ControlMk with no success.

Is there any software that can force radial deadzones or can I somehow tweak something physically on my controller?
