Hello, I’m trying to use an Arducam 16MP IMX519 Motorized Focus USB 3.0 Camera Module) connected to a Jetson Nano via a USB hub, but I’m facing the problem of freezing after taking 100 frames, at 101 images it freezes, it doesn’t depend on the resolution, it actually affects just the number of frames per freeze rate. After freezing, the camera stops responding and can only be fixed by physically reconnecting to the hub. I’ve tried over 10 different hubs and none of them work consistently on the Jetson Nano, while Windows 10 works great.
The result of viewing connected USB devices:
jetson@nano:~$ lsusb -t

dmesg after working with the camera:

Found the following for this problem but failed to apply it. Maybe you can tell me how to replace BULK with ISOC for testing?

The pipeline with which I start the camera:
gst-launch-1.0 v4l2src device=/dev/video0 ! "video/x-raw, format=YUY2, width=4656, height=3496, framerate=9/1" ! xvimagesink
I also tested through qv4l2, the problem persists, the hang is accompanied by the following:
jetson@nano:~$ qv4l2
Opening in O_NONBLOCKING MODE
Opening in O_NONBLOCKING MODE
v4l-convert: error short yuyv data frame
error
Opening in O_NONBLOCKING MODE
Error White Balance Temperature: Input/output error
Error Exposure (Absolute): Input/output error
Also, I had doubts about sufficient power, so I installed a separate power supply at 5.2 V, here is the result of looking at the input voltage in the Jetson Nano:
jetson@nano:~$ sudo cat /sys/bus/i2c/drivers/ina3221x/6-0040/iio\:device0/in_voltage0_input
5200
Perhaps you have encountered the connection of similar USB cameras through hubs, which can cause freezes? Or how can you bring the video display to the level of the Windows OS?
Thank you in advance!
