Any HID (Human Input Device) compliant joysticks can be used. XBox 360 game controllers have two joysticks, a D-pad and a number of buttons. The joystick portion is the same as any other joysticks or game controllers. However, the button mappings are different. Here is the button map I used:

#define Btn(n)                  (1 << (n))
//
// Logitech Joystick:
// UsagePage=0x01, Usage=0x04
//
#define Logitech_Trigger        Btn(0)
#define Logitech_Btn2           Btn(1)
#define Logitech_Btn3           Btn(2)
#define Logitech_Btn4           Btn(3)
#define Logitech_Btn5           Btn(4)
#define Logitech_Btn6           Btn(5)
#define Logitech_Btn7           Btn(6)
#define Logitech_Btn8           Btn(7)
#define Logitech_Btn9           Btn(8)
#define Logitech_Btn10          Btn(9)
#define Logitech_Btn11          Btn(10)
#define Logitech_Btn12          Btn(11)
//
// Microsoft SideWinder Joystick:
// UsagePage=0x01, Usage=0x04
//
#define SideWinder_Trigger      Btn(0)
#define SideWinder_Btn2         Btn(1)
#define SideWinder_Btn3         Btn(2)
#define SideWinder_Btn4         Btn(3)
#define SideWinder_BtnA         Btn(4)
#define SideWinder_BtnB         Btn(5)
#define SideWinder_BtnC         Btn(6)
#define SideWinder_BtnD         Btn(7)
#define SideWinder_Btn9         Btn(8)
//
// Microsoft Xbox Game Controller:
// UsagePage=0x01, Usage=0x05
//
#define Xbox_BtnA               Btn(0)
#define Xbox_BtnB               Btn(1)
#define Xbox_BtnX               Btn(2)
#define Xbox_BtnY               Btn(3)
#define Xbox_LB                 Btn(4)
#define Xbox_RB                 Btn(5)
#define Xbox_Back               Btn(6)
#define Xbox_Start              Btn(7)
