What to do if the USB camera cannot be listed?

Questions

After about 10 seconds of powering on the camera, list the available cameras by running the executable file ListDevices.exe , which is compiled from the Percipio SDK sample program, using Windows PowerShell. But the camera cannot be found in the enumerated list of cameras.

Causes and Solutions

Possible causes and solutions are listed below:

  • Camera initialization exception

    The camera can only be listed after initialization is completed. The normal initialization process of a USB camera is below: When the USB camera is powered on, the power light on the body flashes rapidly, and after initialization is completed, it flashes at a frequency of 1Hz. The entire process from power-on to initialization completion takes about 10 seconds.

    If an initialization exception occurs, please do the following:

    1. Power off and reboot the camera.

    2. If initialization is still abnormal, please check the hardware:

      • If the host computer, host computer USB connector, or USB cable is abnormal, please replace the corresponding hardware.

      • If the camera is malfunctioning, Contact Percipio technical support.

  • (Windows operating system) USB driver not installed or driver installation abnormal

    For instructions, see Install USB driver.

  • (Linux operating system) Permissions not set

    For instructions, see Set USB Camera Access Permissions.
