[k4a_ros_device_node]: Failed to poll cameras: node cannot continue. #249
Comments
Hi there, |
Hi, I downloaded the Kinect SDK 20.04 like two months ago. I think I got it from here. |
Thanks for the comment - We're working on official support on 20.04 for the SDK. |
@ooeygui Hi, actually it happens when i use ubuntu 18.04 |
Hi, finally I changed a laptop and this error did not happen again. Both of the laptops use ubuntu 20.04. |
@AlezzzRd @ooeygui @empty-spacebar @sverrejoh |
I have solved this issue. Chang a usb3.2 gen2 line. It is because of usb port or usb line |
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 usedk4aviewer
, 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.
