USB camera and IMX219-160 Camera issue

[tun69093]

I would like to test 2 camera at the same time, but it seems like I cannot do it.
Is there any drivers that I have not setuped?

IMX219-160 Camera:

from jetbot import Camera
from IPython.display import display
import ipywidgets.widgets as widgets
from jetbot import bgr8_to_jpeg

USB camera:

from jetcam.usb_camera import USBCamera
camera = USBCamera(width=224, height=224)
camera.running = True
from jetcam.utils import bgr8_to_jpeg
import traitlets
import ipywidgets
image_w = ipywidgets.Image()
traitlets.dlink((camera, 'value'), (image_w, 'value'), transform=bgr8_to_jpeg)
display(image_w)

It always shows me the error for USB camera.

During handling of the above exception, another exception occurred:

Thanks a lot!

Have a check the resolution by v4l2-ctl --list-formats-ext to modify the width/height to try.
