What to Do If Your USB Camera Isn’t Working with the USB Ports

CommBox touchscreens now support USB 3.0, enabling high-quality video conferencing with compatible webcams. If your USB camera isn't working as expected, follow these steps to troubleshoot and ensure optimal performance.

Applies To

CommBox S4, S5, Atom, Intelligent Display

Step-by-Step Instructions

Step 1

Verify USB Port Compatibility

  • Ensure you're connecting your USB camera to a USB 3.0 port (note that all USB ports are 3.0) on the CommBox screen.

  • USB 3.0 ports are typically marked with a blue insert.

  • Using a USB 3.0 port is essential for high-definition video streaming and optimal camera performance

Step 2

Check Camera Specifications

  • Confirm that your USB camera supports USB 3.0.

  • Some high-resolution webcams require USB 3.0 for full functionality, including 1080p or 4K video streaming.

  • Refer to your camera's user manual or manufacturer's website for compatibility information.

Step 3

Connect the Camera Properly

  • Plug the USB camera directly into the CommBox screen's USB 3.0 port.

  • Avoid using USB hubs or extension cables, as they can cause connectivity issues or degrade video quality.

  • Ensure the connection is secure and the camera is powered on.

Step 4

Configure Camera Settings

  • Access the video conferencing application you're using (e.g., Zoom, Microsoft Teams).

  • Navigate to the settings or preferences section and select your USB camera as the default video input device.

  • Test the camera within the application to confirm it's functioning correctly.

💡 Tip: If your camera supports UVC (USB Video Class), it should work seamlessly with most video conferencing applications without the need for additional drivers.

  • Camera Not Detected?

    • Try connecting the camera to a different USB 3.0 port on the CommBox screen.

    • Restart the CommBox screen and reconnect the camera.

    • Test the camera on another device (e.g., a laptop) to ensure it's functioning properly.

  • Poor Video Quality?

    • Ensure you're using a high-quality USB 3.0 cable.

    • Check the camera's resolution settings within the video conferencing application.

    • Close any unnecessary applications that may be consuming system resources.

  • Audio Issues?

    • If your camera has a built-in microphone, verify it's selected as the default audio input device in your application settings.

    • Test the microphone to ensure it's capturing audio correctly.
