Someone, I need help. My USB devices started to disconnecting and reconnecting after a second. It happens randomly, and I don't know what it is related with.This issue occurred after I clean my PC.

USB 3.0 randomly disconnecting and reconnecting, not power config

So I have a Surface Pro 3 running Windows 10, and an external USB 3 HDD. If I plug in the HDD, a process will begin. First the drive will appear with the drive letter only, and be unreadable, but in an unusual way. Any software that attempts to interact with it will hang until it either crashes or the drive is disconnected. During this stage the drive may disconnect and reconnect multiple times. If left in for long enough, the drive will finally show up with it's name, and be readable. However it still disconnects and reconnects.

Steps I have tried:

• Disabling the power saving features for all USB devices in Device Manager
  
• Reinstalling all USB drivers
  
• Testing hard disk on my desktop computer (where it works fine).
  
• Powering down the drive for an extended time before trying again
  

 

USB randomly disconnecting and reconnecting

Hello, I'm Jan and I'm happy to help you today. I'm sorry that you are experiencing this problem with the USB device. That popup error Unknown surge on USB port Unknown USB device needs more power than the port can supply" can also indicate that the USB device is faulty or there is a problem with the USB ports. This is most likely the cause why the USB devices randomly disconnect and reconnect.

If you are using a USB HUB try to plug in the USB devices directly to the computer.

1. Try using each of your USB devices on another working computer to check if the error will appear. If yes, most likely the USB device is faulty.

2. Press Windows key + X

Select Device Manager

expand Universal Serial Bus controller

Select the USB root hub controllers from the list

uninstall the drivers

then restart your computer.

3. Power cycle your computer.

Shutdown the computer

and unplug the power cables

Then press and hold the power button for 30 seconds.

Plugin the power cables

then power on the computer

Then try to plug in the USB devices.

4. Download the latest drivers or chipset drivers from the Manufacturer's support website.
