Yesterday, the USB flash drive broke down. I got a lot of USB flash production tools from the Internet. I don't know which niuyun software it was. I broke my USB drive. tnnd is really depressing, today, I made a day to thank the Zhongguancun blog for its article "Rainbow Miracle". I finally finished it and I am posting it to share it with you!
At first, I thought the mouse was broken and I couldn't find any other USB devices. Then, we thought that the USB device may be disabled due to a BIOS setup problem. Reboot the device and enter the bios again. after entering the system, all USB devices found in device management are displayed with a yellow exclamation point. Are all USB interface drivers suspended? Reinstall the motherboard driver and install the driver through the System Disk boot.
In the properties of the USB device in the Device Manager, the message "Windows cannot start the hardware device because its configuration information (in the Registry) is incomplete or damaged." is displayed ". The Registry is broken. After query, the solution is as follows:
Method: Open the Registry Editor (start -- run -- Regedit ), expand HKEY_LOCAL_MACHINE/system/CurrentControlSet/control/class/in sequence. There are a lot of items enclosed by "{}", which are clicked one by one, check whether the text "Universal Serial Bus controllers" is displayed in the right window. Find the "upperfilter" or "lowerfilter" item in the right window and delete it, then, go to the Device Manager and delete all the devices with exclamation marks under the Universal Serial Bus Controller. Then, scan the hardware installation again to restore the device.
