Xbox controller sync

Sync the Controller:
To sync a wireless controller with your Xbox, follow these steps:

Press the Xbox button on the controller to turn it on.
Press and hold the small sync button on the front of the Xbox Series X console (located near the USB port).
While holding the sync button on the console, press and hold the sync button on the controller (located on the top near the Xbox button).
Release both sync buttons when the controller's Xbox button starts flashing. The controller should now be synced with the console.

You have to sync your second controller, via the Xbox One's sync button on the left, and the controller's sync button on the top.

You have to push the sync button on the controller (Next to LB bumper) and the sync button on the front of the Xbox 360 at the same time for the controller to sync properly.

The old controller work with the Xbox 360 slim. Have you been following these steps to sync your controller?:

To sync them up, power on the Xbox and the controller. Then push the sync button on the Xbox (small black button next to the USB ports on the front), then push the sync button on the controller (location varies depending on the type of controller). When
you push the sync button the green light will spin in a circle (on both the Xbox and the controller). If the light doesn’t spin in a circle then it isn’t in sync mode and you might have a problem with the controller.

I did this with my own Xbox slim and my old controllers so I know it is possible.



Here is a youtube video of someone showing it work/how to do it: http://www.youtube.com/watch?v=pWGdw_oi0Xc



Hope it works! Happy gaming!

Have you tried re-syncing your controller to the xbox by pressing the sync buttons on both the console and the controller?
