Can You Connect a USB Camera to Xbox 360?

No. Xbox 360 does not support standard UVC (USB Video Class) webcams. The OS lacks drivers and the API for apps to access generic USB cameras.

Only Official Camera

• Xbox Live Vision Camera (2006) – Proprietary USB device (1.3MP, fixed focus, mic array). Used for Video Kinect (pre-Kinect video chat), Uno, Texas Hold'em, TotemBall. Discontinued, hard to find, 480p max.

Workarounds (Not Native)

• Capture Card + PC: HDMI/Component from 360 → Capture Card → OBS → Virtual Camera (OBS VirtualCam) → Discord/Zoom on PC. 360 still can't "see" the camera.
• Kinect (Xbox 360): Depth camera + RGB + Mic array. Supported in dashboard (gesture nav, video chat via Video Kinect) and specific games (Kinect Adventures, Dance Central, Skyrim shouts). Best option for "camera on 360."

For streaming 360 gameplay with facecam: Capture card + PC webcam + OBS. The 360 itself cannot use a USB webcam.
