Using Keyboard And Mouse on Xbox One S

Some games on the Xbox One or Series X|S do support keyboard and mouse. So if you use a keyboard and mouse just by plugging them into the usb ports on the Xbox console, then no it is not a bannable offense. It can be though if you use an unofficial adapter to play on games that do not support keyboard and mouse.

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

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.

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.
