Hi Laurent, I heard of that there was a chance between you and Sylwester telling about the menu entries focus, and so after that, probably this menu style of the patch I sent, need to be more upgraded. So, can you tell me the kind or sequence of the UVC device breifly? I guess the word *AUTO* at the UVC device means doing focus continuously, not once or one time. But, at the sensors I used the *AUTO* focus means doing focus once, on the other hand *CONTINUOUS* means doing continuously. So, we need to be clear terms about focus. At the sensor I used, the focus needs 3 kinds of commands: 1) setting mode : it makes the lens initial position for each AF(Normal, Continuous, Night mode Focus, etc), and set the AF status Idle. 2) execute AF : doing the move of the lens 3) read AF status : checking the lens status(Focus failed, Focus success, Idle, Busy) and do the proper jobs. I don't know uvc case well, so, If you share about this, it can be help.
