Wired controller doesn’t work

You might need to update your controller.

  Follow these steps to update your controller wirelessly and to support the Xbox One Stereo Headset Adapter:
  
  1. Sign in to Xbox Live on your Xbox One console and install the latest system update if prompted to do so.
  2. If you have a stereo headset adapter, plug it into the bottom of your controller so it can also get updates.
  3. If you're using a stereo headset adapter, plug in a headset (a headset must be plugged in so the adapter will turn on).
  4. Press the Xbox button to open the guide.
  5. Select System > Kinect & devices > Devices & accessories, and then select the controller you want to update.
  6. Select Device info, select the Firmware version box, and then select Continue.
  7. When the update is complete, you can update additional controllers. If they can only be updated via USB, see Update
     via USB. Otherwise, select the Update another button on the screen after the first update is complete, and then follow the steps.
  
  
  
  Notes
  
  • The auto-detect feature of this update may not work immediately if you plugged your stereo headset adapter into the controller while downloading a system update, or while the console was turned off. To resolve this, go to the Home screen and unplug the
    adapter. Then, re-plug the adapter into the controller.
  • You only need to update your controller one time to use the stereo headset adapter. However, if you plan to use the stereo headset adapter with other Xbox One controllers, you’ll need to follow this process for each controller. Additionally, check for new
    updates periodically as Xbox frequently ships new controller features and improvements.
  • If you try to update a controller that was already updated, the system will check the controller and proceed to the success screen within a few seconds to indicate that it’s already updated.
• Update via USB
  
  Follow these steps to update your controller via USB and to support the Xbox One Stereo Headset Adapter:
  
  1. Sign in to Xbox Live on your Xbox One console and install the latest system update if prompted to do so.
  2. If you have one, plug the stereo headset adapter into the bottom of your controller so it can also get updates.
  3. If you're using a stereo headset adapter, plug in a headset (a headset must be plugged in so the adapter will turn on).
  4. Plug the big end of the included USB cable into the port on the left side of the console, around the corner from the disc tray.
  5. Plug the small end of the USB cable into the top of the controller.
  
  
  
  1. Instructions to install the update should automatically appear. Follow the instructions, and don’t disconnect the USB cable while the update is in progress. (The process can take up to 3 minutes.)
     
     If instructions to install the update don’t automatically appear, you can start the process manually. To do this, press the Xbox button to open the guide, select System > Kinect & devices> Devices
     & accessories, and then select the controller you want to update. Select Device info, select the Firmware version box, and then select Continue.
  2. When the update is complete, unplug the USB cable. If you have additional controllers to update, connect them now, one at a time, select the Update another button on the screen, and then follow the steps.
  
  
  
  1. Press the Xbox button on the wireless controller to turn it on. Your controller is now up to date, and you’re ready to use your Xbox One Stereo Headset Adapter.

  • If you try to update a controller that was already updated, the system will check the controller and proceed to the success screen within a few seconds to indicate that it’s already updated.
  • If you have more than one controller connected via USB cable, the update will tell you to disconnect the other controller and update just one controller at a time.
• Update via PC
  
  Update your controller on a Windows 10 PC by using the Xbox Accessories app:
  
  1. Get the app from Microsoft Windows 10 by searching for "Xbox Accessories."
  2. Launch the Xbox Accessories app.
  3. Connect your Xbox One Wireless Controller by using a USB cable or the Xbox Wireless Adapter for Windows.
     
     Note You'll be prompted to update to Windows 10 Anniversary Edition if you haven't yet done so.
  4. When the controller is connected, you'll see the message Update Required if an update is mandatory. Install the update.
     
     Note You can also go to Device Info to check for an update.
  Notes
  
  • The Xbox Accessories app is available only on Windows 10.
  • Controllers that don't have a built-in 3.5-mm audio port must be updated using a USB connection and must have the Windows 10 TH2 Update (or later).
  • Updating the controller over Bluetooth is not supported.
  • Bluetooth requires a PC running the Windows 10 Anniversary Update. See Windows Update: FAQ to learn how to get the latest Windows update.

Hello Fawn!

Can you be more specific to what controller and on which console before we can further troubleshoot your issue.

Thanks!

Try performing a hard reset EXACTLY like this. Hold the power button on the console for 8 seconds or until the power shuts down completely.
Unplug the power cord from the back of the console for 5 minutes.
Plug the power cord back in and restart the console.

That's very weird. But it also happened to me and there was a problem with the USB cable.

Try more types of cables and then it will work.

Check your connections . Mine acts up sometimes . I just unplug and plug in
