Is your FX3 UVC firmware developed based on the example project associated with AN75779?
If not, please refer to the above-mentioned example project.
Could you tell what is the command you are sending from PC to camera?
Is the video streaming seamlessly without any freeze?
Are you observing any error logs on the UART terminal? If yes, could you please share it.
Thank you for the information.
I will try to confirm about AN75779.
