1、下载联想b460摄像头驱动

http://support1.lenovo.com.cn/lenovo/wsi/usercenter/computersearch/StandardMyComputerSearch.aspx?id=WB00958907&showradio=1&showdriver=no

到上边的网址找到摄像头驱动，下载到本地。

2、下载后解压

解压时出现 No Matched Device Driver 错误提示，点确定忽略它。

找到解压后的10.Camera文件夹

里边包含文件夹：Bi_1.10.119.1、Bi_6.x.2018.15、Chi_1.10.129.1、Chi_2.10.129.1、Su0.3M_1.0.7.1、Su1.3M_1.0.7.1

CmDrvLdr.exe应用程序

CmDrvLdr.ini配置文件和preset、SilentInstall两个dos批处理文件。

3、出现No Matched Device Driver错误提示的解决方法

会出现No Matched Device Driver错误提示是因为：

联想官方为了方便在一个摄像头驱动包中压缩了多款驱动，然后用一个CmDrvLdr.ini文件来引导exe程序的选择相应的驱动安装

但是引导出错，所以就会出现No Matched Device Driver!这个错误提醒

解决方法：http://support1.lenovo.com.cn/lenovo/wsi/htmls/detail_13007486222343211.html

解决方法就是通过查找摄像头驱动的硬件ID直接安装相应的驱动，因为用CmDrvLdr.exe会因引导失败而安装不上驱动。
