Windows 10: USB Port stops & starts working - and no logs

Hi all, My System is ... - Lenovo T14 Notbook - Windows 10 Pro 20H2 I have two USB ports on the Notebook and one has a problem that I don't understand. When I do have a USB memory stick connected it stops working - without any warning or anything else (just that sound like manually unplugging the stick). After some time (usually in the range of seconds) it starts working again - I hear the nice sound about a new device and the Explorer windows with the new connected drive. It happens only on the one USB Port. It happens not only with one specific USB memory drive but others as well. How can I find the cause of that problem? - Windows update tells me: You're up to date. - In the device manager I can't see any problematic device (with yellow exclamation mark) - When the device is "not working" I do not see the "USB Mass Storage Device" in the USB controllers tree in the device manager I was thinking about the Event viewer to see what s going on. But in the sub tree "Hardware Events" I don't see anything - but there is where I do expect more information. What can I do to get more information and how to fix it. KR, Max

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.
