Alright, this is what I have in ControlMK
This should help OB to recognize the right stick.. other buttons you may have to map yourself.
X- : VK_A
X+ : VK_D
Y- : VK_W
Y+ : VK_S
Z Axis: MOUSE_RIGHT_CLICK
Z Axis: MOUSE_LEFT_CLICK
X Rotation -: MOUSE_MOVE_X_NEG
X Rotation+: MOUSE_MOVE_X_POS
Y Rotation-: MOUSE_MOVE_Y_NEG
Y Rotation+: MOUSE_MOVE_Y_POS
Z rotations can be left blank.
Copy this over what is in your ini file(Oblivion_default)
iJoystickMoveFrontBack=2
iJoystickMoveLeftRight=1
fJoystickMoveFBMult=0.7500
fJoystickMoveLRMult=0.7500
iJoystickLookUpDown=5
iJoystickLookLeftRight=4
fJoystickLookUDMult=0.7500
fJoystickLookLRMult=0.7500
If problems, try using 2.0000 instead of 0.7500
Mouse sensetivity may need to be raised a little as right and left stick are working off of the mouses settings and the speed might be slowish.
Result? Your right stick should now take proceedance over the mouse(but you can still use the mouse for movement)
Hope that works.
