Joystick sensitivity

[JeffyB]

Hi. I'm currently using a USB Xbox 360 controller with Dolphin. The joystick is too sensitive which makes precise aiming very difficult--it either doesn't move or it moves too fast. I recall I also had this problem on the Project 64 emulator, and I even notice it in the "Test" tab of the controller's properties in Control Panel. Is pressing the button assigned to the modifier the only workaround?

I figure this is a common problem, but I don't know if there is any better solution for it...
