+When not activated, the MotionPlus is detected by regular polling (every 8 seconds or so) of 0x(4)a600fe. Writing 0x55 to 0x4A400F0, then 0x00 to 0x4A400FB (the standard extension init, works fine even with no extension) re-activates the standard extension, if any, plugged into the MotionPlus pass-through port. The development version of the [[CWiid|CWiid driver]] currently implements this method (without automatic 8 second checks) on the [http://abstrakraft.org/cwiid/browser/branches/motionplus/ motionplus branch]. Additional information on MotionPlus workings and implementation requirements are at http://abstrakraft.org/cwiid/wiki/MotionPlus.
{{note|There is no requirement to use the correct mode for the extension, but otherwise the bitshift/move wouldn't make sense. Using the Nunchuk in classic controller mode would clobber a significant bit in the middle of the Z acceleration. Using the Classic controller in Nunchuk mode would clobber some of the buttons.}}
