Use the table below to identify the issue you are experiencing and find the recommended troubleshooting steps
|
Symptom |
Possible Cause |
Recommended Action |
|
Camera is not detected by the computer |
UVC is disabled, incorrect USB port, incompatible cable, or computer permissions are blocking the camera |
Verify that UVC is enabled, reconnect the camera, test another USB port or cable, and check the computer’s camera permissions |
|
Camera is detected, but no video is displayed |
Unsupported USB resolution, application permissions, or incorrect camera settings |
Verify the camera’s USB output resolution and frame rate, check application permissions, and test the camera in another video application |
|
Video is freezing, lagging, or dropping frames |
Insufficient USB bandwidth, incompatible USB standard, long cable, or multiple USB devices using the same USB controller |
Use a compatible USB 3.0 connection, disconnect unnecessary USB devices, and test with a shorter or known working cable |
|
Video resolution or frame rate is limited |
The computer, USB port, cable, hub, or application does not support the selected USB output format |
Verify the USB specifications and supported resolutions of all connected devices |
|
Camera disconnects or reconnects intermittently |
Loose or damaged cable, insufficient power, unstable USB hub, or connection issue |
Reseat the USB cable, test another cable or USB port, and bypass any USB hubs or adapters |
|
Camera works when connected directly but not through a hub or adapter |
The hub or adapter is incompatible, does not provide enough power, or does not support the required USB standard |
Test a compatible powered USB hub or connect the camera directly to the computer |
|
Camera is not recognized after changing USB settings |
The camera or computer may need to be restarted |
Power cycle the camera, restart the computer, and reconnect the USB cable |
|
USB issue continues after completing the basic checks |
Camera settings, computer settings, or hardware may require further troubleshooting |
Restart the camera and computer, perform a factory reset if necessary, and contact BZBGEAR Technical Support |
