playing while the controller is connected via wire

I am experiencing a problem which may be related. While I am not having any issues with it charging, I do sometimes use my controller wired. I remove the battery and connect it via the play and charge lead as my son, who is quite young, finds the controller
a bit heavy with it in.

For some reason, since the update, I am having a hard time getting the controller to work while wired. It lights up and the LED is solid indicating a connection. However, it will not operate the console. The only way I have found to get it working again
is to unplug the cable, reconnect the battery and connect the controller via wireless. I have tried several leads, all to no avail.

Is your controller connected via Bluetooth connection, wireless connection, or via USB?

Kindly try connecting it using a wired connection.

it's a firmware issue, Plug the controller in via USB and open settings, go to system and select "update controller". there's still a few niggles but it sorts most of the headset issues out.

It does not disconnect while it's wired as it works like any other USB controller and does not use the wifi connection. been playing with my controller plugged in and no batteries for days now

Yes it will. You can connect the controller to your PC via WiFi or Bluetooth and can connect via your plug and charge kit to charge the batteries while you're playing.

But for playing on PC you don't even need the play and charge kit, you can just connect your controller via micro USB cable to your PC even if your batteries are drained as while connected via USB it wont use batteries.

^^Yep. A while before the Xbox One launch, MS was granted a patent on a wireless controller that turns into a wired one when connected with a cable.

When the Xbox One controller is connected to the console via a USB cable, the commands are sent through the cable, rather than through wireless, and you can test that by removing the batteries and you'll find it still works. So, the answer to your question
is almost certainly no, as there is no need for a separate wired controller as the one you already have already works as both a wired and wireless controller.
