Windows 10: USB ports not working, No power delievery.

The wires i used and the devices used work well with everything else.

Except 2 ports on the back with a power sign, none of the 6 other ports do not work.



I tried everything i can find online. No progress.

The ports used to work till yesterday. Also, I'd be seeing this "Power surge on USB" error even if i pull out all the USB peripherals incl. keyboard and mouse.


Additional info: The one of the wires i use to connect has a light which doesn't light up when connecting to any of the 6 other ports which do not have a power button symbol on them and the ports which have power button symbol work just fine.


System : DELL Optiplex 3040.



Looking for a fast reply. Thanks in advance!

USB port not working

I have an HP Pavilion dv6604nr laptop. I have 3 USB ports, 2 located on the left side and one located on the right side near the power supply port. For some reason, one of the USB ports on the left hand side will not recognize anything that is plugged
into it. I have done all the steps and suggestions that is posted on this site, and still can't get it to work. The message I get is "The last USB device that was connected has malfunctioned and Windows does not recognize it." It shows in the Device Manager
as Unknown USB Device(Port Reset Failed). When I have a USB device plugged into the non-working port, it shows up in the Devices and Printers folder, but the device does not work. I am at my wits end. Can anyone help me or suggest any other things to try?
Oh, I am running Windows 10 pro.

 

Power Surge on the USB port?

Hi Bob,

When a user tried uninstalling the USB drivers, it usually installs itself again when the computer restarts. It is a fact that most of the Mouse and Keyboard nowadays are connected using USB connection instead of their traditional PS/2 port. We suggest that
you visit the link provided and follow the steps provided:
USB has malfunctioned and exceeded the power limits of it's hub Port , you should disconnect the device

Kindly let us know if you need further assistance.

 

USB ports

Hi Frank,

Inserting and removing a USB device repeatedly may cause the USB port to stop responding. When the port is in this state, it no longer recognizes any USB device, and the USB device will not work.

Here are few things that you can do to resolve the issue:

Use Device Manager to scan for hardware changes. After your computer scans for hardware changes, it might recognize the USB device that is connected to the USB port so that you can use the device.

To scan for hardware changes, follow these steps:

• Click Start, and then click Run.
  
  Note If you are running Windows Vista, click Start, and then use the Start Search box.
• Type devmgmt.msc, and then click OK. Device Manager opens.
• In Device Manager, click your computer so that it is highlighted.
• Click Action, and then click Scan for hardware changes.
• Check the USB device to see whether it is working.

Turn off Allow the computer to turn off this device to save power.

• In the Device Manager dialog box, expand Universal Serial Bus controllers, right-click USB Root Hub, and then click Properties.
• In the USB Root Hub Properties dialog box, click the Power Management tab. Uncheck the
  Allow the computer to turn off this device to save power
  box.
  

Let us know how it goes after performing the suggested troubleshooting steps.
