If you are having a hard time connecting your USB device to windows 10, instead of the normal way it works, your screen is showing a pop up that says “Power Surge on Hub Port – Unknown USB Device needs more power than the port can supply.” If you further expand it, you could see more details. This is not good, it signifies something wrong and can be frustrating.
First, let’s look at the reason why this happens. In normal circumstances, the USB devices have a limit to the amount of power they can draw from the USB port of a computer system, which is a maximum of 500 milliamps on each connection. However, something might go wrong and the USB draws more power than is required, that is when this error message pops up, and the connection is aborted. When this happens you cant be able to have access to the data the USB device contains.
What could cause this problem? Is it a problem with my computer USB ports or is the USB device faulty? The problem could be as a result of any of these. You don’t need to bother much because this is a common problem and there are ways to fix it easily.
