How to browse for existing device driver?

Question

我有一台指纹扫描仪， 未能识别但其他的是美好的。那么我该如何查找工作阅读器的驱动程序/inf 文件，以便与无法识别的设备配合使用？

当我尝试手动浏览驱动程序时，我无法在列表中找到制造商？

Device that is recognize

Device that is not recognize

EDIT

I have 2 Futronics Fingerprint Scanner (USB interfaced). They are both working fine, but one day, one if the scanners suddenly not recognize. I already tried :

1. uninstall the driver and restart the pc
2. Plugged the scanner to other computer
3. Plugged the scanner to other port

But nothing works.

Now I want to browse the driver of the working scanner and use it to the scanner that does not recognize, but I don't know where it is located.
