Windows 10: USB ports stopped working

Hello everyone, I have a Samsung Odyssey laptop with Windows 10 and all of its USB ports stopped working after a sudden blue screen error a few days ago.I've already tried A LOT of solutions that I found on the internet, but none of them worked for me.In Device Manager > Universal Serial Bus Controllers, there's only the device USB xHCI Compliant Host Controller, and it has a yellow exclamation point. I also unistalled this device and restarted the computer or select 'Scan for hardware changes' several times, but it still has the yellow mark on it. And I cannot update its driver becaus

USB port stopped working

I had a USB2 port on the front panel that was working for a year but then one day it was not. I uninstalled / installed the device via Control Panel for both of the USB Composite Device listings but it made no difference. I thought it may be a bad connection but everything looked OK. Both ports had power according to a USB digital voltmeter. On the motherboard I moved the cable going to the front panel from one of the USB 2.0 Headers to the other Header & everything worked. At least for a couple months. Now the same port on the front panel does not work again. So I uninstalled / installed both USB Composite Device listings but it made no difference. Under Properties it says they are working properly. In Control Panel I did not touch the USB controllers for either USB 3.0 listing or for the USB Printing Support. The port was working a few days ago but now it is not. The only thing that really happened lately was a Windows 10 Security Update that was installed on 10-27-2022. Could that have changed something? Anything is possible but it seems strange that the same front panel port stopped working no matter which mobo header is used. Could one of my USB thumb drives be going bad & when plugged in is shorting out something on the motherboard? Any ideas & suggestions would be greatly appreciated. Thanks

 

USB 2.0 Ports Stopped working

Hello,

I recently noticed my USB 2.0 ports have stopped working, but my USB 3.0 port is functioning perfectly.

Steps i have tried:

- Restarting

- Searching for device changes in Device manager

- running troubleshooter

all these suggested fixes didn't remedy the issue, its a bit of an inconvenience that i only have one functioning USB port

Thanks

 

My usb port stop working

Hello,

This is Sudha Independent Advisor and user like you. Please follow below steps to solve your issue

Method 1: Use Device Manager to scan for hardware changes

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:

1. Click Start, and then click Run.

Note If you are running Windows Vista, click Start, and then use the Start Search box.

2. Type devmgmt.msc, and then click OK. Device Manager opens.

3. In Device Manager, click your computer so that it is highlighted.

4. Click Action, and then click Scan for hardware changes.

5.Check the USB device to see whether it is working.

If scanning for hardware changes fixed the problem

Method 2: Disable and re-enable the USB controller

Use Device Manager to disable and re-enable all the USB controllers. This lets the controllers recover the USB port from its unresponsive condition. The USB controllers represent the USB ports in Device Manager. If you are not comfortable with advanced troubleshooting,
try the steps in the "Workaround" section.

To disable and re-enable the USB controllers, follow these steps:

1. Click Start, and then click Run.

Note If you are running Windows Vista, click Start, and then use the Start Search box.

2. Type devmgmt.msc, and then click OK. Device Manager opens.

3. Expand Universal Serial Bus controllers.

Note You might have to scroll down the list to find this item.

4.Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.

5. Repeat step 4 for each USB controller that is listed under Universal Serial Bus controllers.

6. Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.

7.Check the USB device to see whether it is working.

If the USB port recognizes the device and if you can use the device, you are finished.
