Solution to failure to find hardware after updating Vista fingerprint Login

Last night, Vista was prompted to have an update and saw a driver like this:

Authentec Inc.-Other hardware-authentec Inc. aes2501a

I believe many of my friends who log on with fingerprints are familiar with it ~

At first glance, I log on with my fingerprint. From the very beginning I didn't like fingerprint login very much, but I was naturally interested in fingerprint login. I think updating will not be a bad thing, so I updated it, later, I was watching the video when I updated it. I remembered that when I watched the video, I heard a prompt of hardware plugging in the system. I thought it was a mouse or a heat sink base, so it may happen unexpectedly, after reading the results, there was no problem, so I had no worries .........

 

When I started the machine today, I touched the fingerprint identification device several times with my fingers. There was no prompt or sound on the result page. It was strange. I looked at the screen carefully and asked if I could not find the fingerprint identification device... Scared, restarted, the problem persists, no way, you can only enter the password to log in to see the situation

Open the Device Manager immediately and check that there is no exclamation point or question mark. The personal identification devices remains safe and sound in the list.

It's strange to open digitalpersona personal and try again. The result also shows that the Fingerprint Recognition Hardware cannot be found and the heartbeat state is lost .. Is it bad? Why not? The HP machine is good. Am I lucky?

So I suddenly thought of updating a fingerprint driver yesterday and immediately checked the update history. Sure enough... It seems that you don't have to worry about it.

The details are as follows:

Authentec Inc.-Other hardware-authentec Inc. aes2501a

Installation Date:

Installation status: Successful

Update type: Optional

Authentec Inc. Other hardware software update released in October, 2008

Then, search for the driver update name on Baidu, and there are few results .... If you don't believe it, you can open Google. Wow, it's really good. There are a lot of results. There are still a lot of Chinese characters that filter out English words. Now Baidu's downhill development is getting worse and worse.

After reading a lot of methods, some say that restoring or reinstalling the system is method 1, but it is also the most stupid

Method 2: The driver is uninstalled and re-installed. This method is slightly better, but it is not a good method.

Method 3: This is the best method. Go to the Device Manager and find the authentec Inc. aes2501a branch under personal identification devices.

Right-click and choose Properties> driver> rollback driver.

OK, problem solving
