Why when I use my keyboard and mouse on a game it either says "controller disconnected"or...

Already have Xbox insider hub. And thanks for the reply. So whats happening is i have my mouse and keyboard plugged in as normal the game loads up, and i cannot see my mouse, i can click start but it thinks im on controller. So if i unplug my controller,
it will say “controller disconnected” which should not happen as i have a keyboard and mouse so, if i go into s game i csn move around with bot keyboard and mouse, but if i click inventoryi cant see my mouse again. Basically if i plug it thinks im on controller
but the mouse is plugged in and i cant see the mouse at all.

Keyboard and mouse support is already here. Having more options is a good thing as not everyone can use a controller. I would say that Microsoft made the correct decision on allowing the developers to decide whether or not their games support mouse & keyboard,
as not every game is suited for controller or keyboard & mouse.

Yes... I have the same.

Mouse freeze, keyboard still working, but if I disconnect the mouse, keyboard and controller from USB and try to connect again, not works.

Eh, I don't know I'm horrible at using keyboard and mouse for gaming, so my opponent would be at an advantage if I used it. I say to each his own, if the game allows it then use keyboard and mouse and vice versa. I love my controllers and I would use them
on pc if I had a bluetooth Xbox One controller.

I've always preferred controllers myself. They're just easier. I've never understood the point of a keyboard and mouse on a console. Why not use a PC if you want to go that route?

because why not have mouse and keyboard on Xbox and i see the common statement all the time mouse and keyboard is unfair to the controller user and that is not the case no one wakes up and is instantly a god with mouse and keyboard just like a controller,
skill comes from practice and more practice i play games like sea of thieves and fornite against pc players and its not that much of a advantage yea button mapping on a keyboard is more in detail but the over all who out shoots who is a myth. it all comes
down to who is comfortable with what and who is confident in there ability to do what they are doing. why not go the PC route because why should i have to i mean games in general should be a player who plays the game should be able to play the game the way
he feels comfortable playing the game. why should i have to go a build a pc in order for me to feel comfortable playing a game. i hate controllers imo i think people who use them are a bunch of casuals who should just stick to single player games and again
that is just my opinion but do i think they shouldn't have a option to play multiplayer no they should have that option but controller fans should not shut out the idea of mouse and keyboard on xbox. on the myth controller users are at disadvantage go watch
people use controllers on pc game like csgo and watch them not going to say it isnt harder because that is personal preference controller users says mouse and keyboard is to hard. mouse and keyboard users say controller is to hard get where i am going here. just
be open minded at what doors this feature will open up. i mean my endgame is not so much mouse and keyboard support on xbox its more about the features it will bring like more cross platform gaming in which i am in full support of. i am willing to play at
a disadvantage of frames per second if it means i can play with my friends on pc. with out going out and spending 800+ dollars on a gaming pc build.
