How can I solve the problem that USB devices cannot be identified in Windows Vista!

When you insert a drive such as a mobile hard disk, mouse, SD card, or MP3, the system prompts you to install the driver. This Sb SYSTEM says it has found the driver of the general volume, there was a problem during the installation, and it could not find the specified file. It was ridiculous that Microsoft had a fix, kb940199, which claimed to be able to solve the problem, but the patch must be genuine, in addition, the installation does not have any effect according to the reaction of other users. During the installation, "the update will not be applied to the system", the update does not apply to your system, I am not using Microsoft's latest and most advanced Vista. How can does not apply to your system ?? As for the problem that USB devices cannot be identified under Vista, this is a problem with the Vista system that has been searched online for two days. many similar problems have occurred since May 2007, I don't know what Microsoft is doing. I haven't completely solved this problem now. I posted a post on Microsoft's msdn discussion board, and I have already replied to several hundred articles. I suggest a variety of solutions, for example, install the patch and delete the infcache.1 file. I tried it one by one and failed to solve the problem until today. I found a solution. I tried it today. Haha, this is really useful. Now my SD card and mobile hard disk can be used. In fact, it is very easy to plug in the computer for the device you cannot recognize, open the Device Manager, right-click the device with question marks, properties, drivers, update and upgrade drivers, search for computers, and change the search path to C:/Windows/winsxs. This is a key step. The system searches for drivers and prompts that the installation is successful, everything is OK. This method proved to be effective on the Lenovo Sunday 210 notebook. I use Lenovo as well. Because it is a problem with the Vista system, it cannot be guaranteed to everyone, all unrecognized devices are valid !!
