相机咨询
目前我板子里的模块如下，只有两个uvc相关的模块。既然您说我缺少相关驱动，所以能否通过邮件直接发送相关模块给我，让我自己安装，谢谢。下面是我板子已经装2个模块：uvcvideo 693400
videobuf2_vmalloc 28771 uvcvideo
我是刚打电话给你，你让我发送邮件到serviece邮箱 您好，打印信息如下的话：

驱动是有的了，你编译一个QT的摄像头DEMO看看能打开吗，你烧写是什么系统

这里是我qt程序界面点击启动摄像头按钮后的结果显示：

HIGHGUI ERROR: V4L: index 0 is not correct! 我的摄像头qt程序打不开板子上的摄像头。但是如果摄像头连接到虚拟机上，且替换成适合虚拟机的opencv库，摄像头是能打开的、 xingyewuyu 发表于 2017-8-31 10:45

您好，UVC摄像头可以的，之前有同事测试QT5，先另一个同事是在UBUNTU16测试OK的

这videobuf2_vmalloc和 uvcvideo模块必须，因为默认有vido0和video1，我删掉了，如有还是向下注册，注册为video2,如下：

我相机插入板子的usb后，下述命令并没有显示camera的信息

下述命令显示我的相机的型号为：SKT-MS500C-125A
root@myimx6ek314:~# dmesg | grep UVC
[ 5.416975] uvcvideo: Found UVC 1.00 device SKT-MS500C-125A (500c:9015)
请问我是不是usb有问题？没有识别出相机？或者是哪里有问题？
板子上的2个usb我都试过了，不能让相机的视频显示出来 我相机插入板子的时候，串口自动显示如下信息：
usb 1-1.2: new high-speed USB device number 7 using ci_hdrc
