标题: usb3.0UVC摄像头不能获取视频和图片
我用板子系统是Linux debian10.toybrick 4.4.194 #16 SMP Thu Apr 8 18:10:29 CST 2021 aarch64 GNU/Linux 摄像头型号：cyusb3065 MIPI图像，用这个USB3.0芯片转接，接到USB3.0接口内核和文件系统均为最新版
我用/usr/share/rockchip-isp里面的实例代码，不能够获取到usb3.0的视频流，用cheese显示/dev/video0 no device found。用  499  sudo v4l2-ctl -d /dev/video0 --set-fmt-video=width=1920,height=1080,pixelformat=YUV422 --stream-mmap=3 --stream-to=/tmp/1920_480.yuv --stream-count=1 命令会卡住。摄像头的信息v4l2-ctl --all --list-formats-ext
