提示找不到合适的驱动

在安装INF文件时，按确定提示找不到合适的驱动，但是不理它按下一步又可以安装驱动，并且最后提示安装完成，设备管理器也提示设备工作正常，，是怎么回事？

设备驱动程序的安装是先查找相同PID、VID的驱动，若没有则查找兼容的驱动程序。你可能安装了一个系统认为是兼容的驱动程序。

PID vid已经配合了，D12的灯也一直亮了
下一步不知道怎么调式了  指点一下

可能是你的INF文件有问题，你再仔细检查一下。

帮我看一下  D12+C52

试试看：
;[SourceDisksNames]
1 = \"Install Disk\",Disk1,,

;[SourceDisksFiles]
T11.sys = 1,,

还是提示无法为这个设备找到一个合适的驱动
