Windows 10: After latest windows update the usb port does not work to supply power to monitor

After latest windows update the usb port does not work to supply power to monitor

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.

Hello ruthives,

Thank you for writing to Microsoft Community Forums.

To address your concern, kindly help us with the below questions.

1. What is the make and model of the computer?
2. Do you read any error message when you connect the device to the USB port?
3. Are you facing this issue with any particular USB port or with all the USB ports?
4. Since when are you facing this issue?

Your device is kept up to date with the latest features by automatically installing the updates in Windows 10. To narrow down the issue, let's go ahead and follow the below methods and see if it helps.

Method 1: I would suggest you to follow the steps to diagnose and repair the USB ports from the article -

Automatically diagnose and fix Windows USB problems.


Method 2: Update USB controllers.

• Right click on the Start menu and select Device Manager from the list.
  
• Narrow down to Universal Serial Bus controllers and update all the USB drivers.
  
• To update the drivers, right click on the each driver and select Update driver.
  
• If that doesn't resolve the issue, I would suggest you to uninstall all the USB drivers from the device manager.
  
• Reboot the PC and it will automatically pick for the latest drivers for your PC.
  

If the issue persists, download and install the latest USB drivers available for your PC build from the
manufacturer's website and see if it works.

Hope it helps.

USB port issue. Not working

Yes, if you have a laptop try to check your power supply

Your laptop’s power supply delivers power to your USB ports. If for some reason, it fails to do this properly, the devices plugged into those USB ports may stop working. Sometimes, this can be fixed quite simply:

1) Unplug the power supply and charger plug from your laptop

2) Restart your laptop

3) Connect your USB device to the laptop again

4) Plug the power supply back in

in another case

Check your power management settings

In order to save power, by default, Windows switches your USB controllers off when they’re not in use, and switches them back on again when they’re needed. Unfortunately, sometimes this approach doesn’t work as intended, and Windows fails to switch your USB
controllers on again.

To rule this out as the cause of your USB woes, just stop Windows from ‘managing’ power to your USB controllers and devices:

1) Open Device Manager (type “Device Manager” in the Windows search field)

2) Expand the Universal Serial Bus controllers branch

3) Double-click the first USB Root Hub device in the list (if you see only one USB Root Hub device, that’s fine)

4) Click the Power Management tab

5) Un-check the Allow the computer to turn off this device to save power checkbox, and click OK.

6) Repeat steps 3-5 for each USB Root Hub device in your list of Universal Serial Bus controllers
