A little learning about driving updates

1. If the driver is similar to a USB keyboard, do not download it from the Internet, because windows already provides. In Windows, the directory where the built-in driver is located is c: \ windows \ winsxs.

Next time, if you encounter an unrecognized device, the lowest cost is to first right-click the device in the Device Manager and select the problematic device. Then, update the driver and choose to install the device from the local directory, the directory is c: \ windows \ winsxs.

2. when optimization acceleration is implemented using optimization software such as 360 security guard or Kingsoft guard, some services required by the system may be disabled, such as the USB-related PNP service.

3. Enter the bios and set all USB-related options to enabled.

 

Conclusion: The above three points are taken into consideration from the driver, third-party software, and bios settings perspectives. This can be used as a way of thinking, if you still encounter it next time.
