Hi.

I have voxl2 mini and USB camera.

system-image: 1.7.1-M0104-14.1a-perf-nightly-20231025
kernel: #1 SMP PREEMPT Fri May 19 22:53:15 UTC 2023 4.19.125

hw version: M0104

voxl-suite: 1.1.2

I am connecting a USB camera to voxl2 mini and receiving video using voxl-streamer.
I disconnected the USB camera from the voxl mini while video was being received.
For testing purposes, I disconnected the USB camera from the voxl mini while the video was being received.

After that, I can no longer receive video using voxl-streamer.
The reason is that the function set in pipe_client_set_camera_helper_cb is no longer called.
How can I make the function set in pipe_client_set_camera_helper_cb be called again?
or
Is it possible to receive a USB camera disconnected event from voxl-streamer?

please refer to this
When you run the systemctl restart voxl-uvc-server command, the function is called normally and the video is received.
