The error message the USB Device has exceeded its hub port’s power limits, or power surge on the USB port frequently appears when you plug some device into the USB port of the system. It can also happen when you already have plugged in some device, and it discontinues functioning suddenly and shows this type of message. In the normal situation, your USB devices are only permitted for drawing a max of five hundred milliamps for each connection from the PC system or from the USB hub.
If the device gets more power than that, an issue is shown to you the present condition, and the connection is ended. This short draw of power by your USB device is detected by your operating system and actions are taken so. So does it denote that the device is faulty? Or is there an issue with the USB ports of the PC? Well, both can be right. We’ll go through the following workarounds one by one and check if we can troubleshoot the problem at hand successfully.

If the above solutions work just for a short time and the power surge on USB port issues come again, you have to check if there’s some issue with your hardware you’re connecting to the PC.
Fix#3: Check The Individual Hardware
If both the fixes mentioned earlier do not help you resolve this issue, then you have to check if there’s short-circuit in any of the connected devices.

Once you’ve reinstalled all the needed device drivers, plug in all of your devices one by one and check which device reasons the power surge on the USB port issue to appear.
If you spot some device, then try to plug it to the backports of the computer. These backports frequently have more power and provide more energy to your device. If it does not help, then you ought to try to plug it to some other PC. If the behavior is still the same, it possibly denotes there’s some issue with your hardware itself. Try to check your hardware or if you have some warranty left, then claim it with the local store.
