Linux 禁用摄像头

1.使用命令查看摄像头信息

root@root-PC:~$ sudo dmesg | grep uvc
[ 8.625446] uvcvideo: Found UVC 1.00 device USB 2.0 PC Camera (0342:9463)

[ 8.833930] usbcore: registered new interface driver uvcvideo
authen@authen-PC:~$

 

2.修改配置文件中的值，禁用摄像头

root@root-PC:~$ cat /sys/bus/usb/devices/1-1.8/bConfigurationValue

1

root@root-PC:~$ 

使用 vi 编辑器把1改为0后保存退出，此时摄像头已经被禁用

 

3.摄像头恢复禁用： 把配置文件的值设置为1，或重启系统
