[FATAL] [1691069372.183638523]: Failed to poll cameras: node cannot continue.

Describe the bug
I am using an MCU external hardware to trigger the Azure Kinect DK（only one camera) in the Sub external sync(slaver mode), and it can be successfully triggered in the SDK. When using the [official ROS package] wired_sync_mode=0(https://github.com/microsoft/Azure_Kinect_ROS_Driver) without modifying anything, it can run. However, after changing the wired_sync_mode=2 in kinect_rgb.launch, the ROS package cannot run properly and and I encounter the error([FATAL] [1691069372.183638523]: Failed to poll cameras: node cannot continue.) shown in the screenshot.

Expected behavior
Azure Kinect DK is waiting to work until pulse trigger.

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

This ROS node is built on the Azure Kinect SDK. The SDK is not supported on Linux beyond 18.04 (microsoft/Azure-Kinect-Sensor-SDK#1263). With the Azure Kinect DK being end of life, the sdk will not be supported on 20.04 or later.
