Microsoft's Xbox 360 gaming console has three USB ports, two in the front and one in the back. You can plug both a keyboard and mouse into the gaming console and still have one more USB port available. You cannot use the keyboard nor the mouse to play games, but you can use them to search the Internet and for messaging purposes on Xbox Live.
Plug keyboard and mouse into the Xbox 360 using the USB connection. The USB from both the keyboard and mouse will only fit into the console one way.
Turn on the Xbox 360. The power button is just above the USB ports on the front of the console; the Xbox 360 automatically recognises both devices.
Connect to Xbox Live by clicking on the "XBox Live" logo on the home screen.
Use your mouse to navigate through Xbox Live. Use the keyboard to fill out forms on Xbox Live.
