Xbox 360 USB Controllers Multiplay Problem

Hello, I'm hoping someone can help, please.

I've just purchased 2 new (genuine Microsoft) USB controllers for my boys. Unfortunately on plugging them in only one works at a time.

They both work individually but both are assigned to player 1 (or somehow today player 2).

As such they can't play multiscreen together. They only play offline games. I've tried different USB ports and they all seem to work individually.

I'm afraid I'm not into gaming so it's possible that I'm doing something daft.

I'd appreciate any pointers. Thanks

:)

 

Unable to use multiple XBox 360 controllers while streaming

I have two XBox 360 wired controllers plugged into two USB ports on my Windows 10 desktop. The controllers work, and I can, for instance, open up Fallout Shelter and navigate around with either controller.

The problem starts when I stream to my XBox One. Suddenly only one controller accepts input. Either controller works in either USB port if it is the only one connected, but with both controllers plugged in, input is only accepted from one of the controllers.

I am trying to play a 4-player game with my two XBox One controllers and two XBox 360 controllers. But for whatever reason I am maxed out at 3 players only since something is blocking the second XBox 360 controller.

 

Both Wired Controllers are Player 1

I just got a xbox 360 and I was trying to play local multiplayer Halo with 4 friends but I was having a weird issue. I have two wired controllers and two wireless controllers. The problem that arises is the two wired controllers always select the same
player making one of them unusable. I tried using all the different USB ports but the problem always persisted. Even after restarting the system. The wireless controllers do no have this issue. Since I am new to the system what am I overlooking?

This guy posted a video of the problem similar to mine (except he has all wired controllers) but I don't see any way to solve the problem. Any help would be appreciated.
