[k4a_ros_device_node]: Failed to poll cameras: node cannot continue.

Hi,

My setups are ubuntu 20.04 and ros2 foxy. I used ros2 launch azure_kinect_ros_driver driver.launch.py to launch the camera driver. In the beginning, the camera and the driver work fine. But like 1-2 minutes after the driver starts, The node will shut down automatically with the warning as follows. [k4a_ros_device_node]: Failed to poll cameras: node cannot continue. After the driver shuts down, I used k4aviewer, and I can see the camera is still running properly. Only the ros2 driver stops. Do you know what reasons could cause this problem? The driver shuts down every time I ran it.

Thanks a lot.

Hi there,
The Kinect SDK isn't officially supported on Ubuntu 20.04.
Can you share the instructions you used to install it?

Hi,
I followed the instructions here.
https://github.com/microsoft/Azure_Kinect_ROS_Driver/blob/foxy-devel/docs/building.md

I downloaded the Kinect SDK 20.04 like two months ago. I think I got it from here.
microsoft/Azure-Kinect-Sensor-SDK#1263

Thanks for the comment - We're working on official support on 20.04 for the SDK.

I have solved this issue. Chang a usb3.2 gen2 line. It is because of usb port or usb line
