Win10 maintenance: how to solve the "surge on the USB port" problem

Some users found that the system has an error message after inserting the USB flash drive. The notification title is “Power surge on the USB port”. How to solve this problem?

Generally speaking, this prompt may be U. There is a problem with the port or a USB device such as a USB flash drive, so the general solution to the problem is to “adapt to local conditions”: If it is a U-port problem, it will report an error, even if it is not inserted, it will report an error (dust and short circuit, etc.); It is a USB device problem, and it will report an error no matter where it is inserted (it may be that the USB device consumes too much power). U disk problem is good to say, big deal is not necessary; if it is a USB interface problem, then every time you insert it may report an error, it is more annoying.
For the USB interface problem, if you want to solve it completely, I am afraid it needs to be checked and repaired. Because the problems are very different, it is difficult to explain them one by one, but at least temporarily turn off the prompts. Fortunately, this time does not need to modify the registry, this problem has been around for a long time, Microsoft has given the native interface.

In Win10, you can turn off the current only option in Settings → Devices & Rarr; USB; if there is a problem connecting to a USB device, please let me know “ (pictured above). This setting item was arranged in the device manager of the control panel in the previous system, and was taken to the Windows 10 settings by Microsoft earlier. It can be seen that the degree of importance is extraordinary.

Users who are still using Win7/Win8.1 can check the related USB devices in the "Control Panel & Rarr; Device Manager & Rarr; Universal Serial Bus Controller" (above). "Don't notify me of USB errors" at the top of the Advanced & rdquo; tab to avoid notifications.
After the above debugging, the notice will no longer appear, but if you want to solve the problem completely, you should still understand the nature of the problem.
What is a surge?
The so-called "surge" is a short-lived phenomenon of strong current and voltage fluctuations. This fault indicates that the computer has a high-power USB device, such as a mobile hard disk, MP3 with USB interface charging function or Mobile phones, etc., when they are connected to the USB interface, there is a large instantaneous power consumption, which exceeds the power supply limit of the USB interface. If the USB interface is not connected to any device, check the motherboard and USB interface, if there is a short circuit fault due to dust or moisture; if the ordinary U disk is plugged in, it will also indicate a power surge problem, which may be a short circuit in the U disk itself. The problem, usually pull out the U disk, pay attention to safely remove the hardware first.
