Hi DRnoam,

I'm SamanthaCheung, a MCP. Hopefully my reply below answer your questions.

1. According to
Xbox One, not all game and app supports mouse and keyboard. For some games and app, the mouse and keyboard support feature need to enabled before you can use it. It's recommended you consult the game or app publisher if you're not sure about this.

2. Almost every USB keyboard work with Xbox One. It depends on the game or the app you'll play on Xbox One. To use a USB keyboard or mouse on Xbox One, you'll need an input adapter. See

How to Use Keyboard and Mouse on Xbox One.

3. Yes. The controller will still be active when you're using the keyboard or mouse. And you can use the controller to configure the mouse.

For the following to work you must make the menu selections using your keyboard. If you use the controller to make your menu selections to start the game you will be placed in a room for those with a controller and your keyboard/mouse will be non functional
to make it fair to other players. To enter the room for keyboard and mouse users the game must be started by selecting the options using the keyboard/mouse. Hope this helps.

Mouse and keyboard support

Fortnite on Xbox One supports the ability to play with a mouse and keyboard. Note that when using a mouse and keyboard on Xbox One, you’ll be placed in a game with other users who also chose mouse and keyboard as their control option. To enable your setup
to use mouse and keyboard, see Mouse and Keyboard Support

Note If you’re on a child account, you’ll also need to enable settings for cross-network play to use a keyboard and mouse while playing
on Xbox One.

Ok, so firstly you should be able to just plug in the mouse/keyboard USB and use it (if they are supported) you shouln't need an adapter to use mouse and keyboard on Xbox One since mouse and keyboard support has been added.

Secondly I'm not aware of black ops 4 supporting mouse and keyboard use on console, so if the developers have not enabled mouse and keyboard support on Xbox One, then using an adapter to be able to use your mouse and keyboard will be considered cheating.

Hi,

A keyboard and mouse, wireless or wired only work on a very limited selection of games (about 30+) for other games it's controller only. All Xbox One games with mouse and keyboard support
