I have a problem with USB communication.
I connect "Camera employing CYUSB3014-BZXI" to PC in use USB cable.
When I send USB Video Class(UVC) command from PC to Camera, it is receive to fail in sometimes.

I supposed that may be caused by Firmware, I am not definite.

Question1:
If Caused by firmware, what does it take for me to solve?

Question2:
What else do you think cause another?

P.S.
I will write this cdc an comment of the same contents in Japanese, to be on the safe side.

=======================================================================

CYUSB3014-BZXIを用いたカメラとUSB経由でPCに接続し、UVCアプリケーションソフトウェアから、
UVCのコマンドを送信すると、まれにアプリケーションSWの設定を正しく受信しないことがあります。
原因として何が考えられるでしょうか。

ICに内蔵したFWの不具合だとしたら、設定値?などで改善できるところはありますでしょうか。

Hi!,

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.
