Windows 10: USB Keyboard is not connecting after unplugged and plugged-in

Hi,


I am using this PC HP for 2 years with same USB keyboard Dell, suddenly yesterday the keyboard was not working, normally USB devices are "Plug & Play" it should connect if unplug and plugged-in but it didn't work so give a try to reboot the machine then keyboard connected again.

but if i unplugged and plugged-in USB keyboard doesn't connect.


* I have tried connecting this USB keyboard on another machine it does connected and also works with un-plug and plugged-in the USB keyboard.

* Also tried new USB keyboard on my machine same problem occurs.

* In windows safe mode the old USB keyboard is connected even un-plug and plugged-in.

Hi,

Thank you for contacting Microsoft Community.

I suggest you to follow the below methods and check if it helps.

Method 1: I suggest you to try the following steps and check if it helps:

• The USB connection may be loose. Try unplugging the keyboard, and then plugging it back in.
• Plug the keyboard into a different USB port.
• If your keyboard is plugged into a USB hub or USB switch box, try removing it and plugging the keyboard into the computer.
• Unplug other USB devices that are not in use.
• Try the keyboard on another computer to verify it is working correctly

Method 2: Also I suggest you to uninstall and reinstall the usb keyboard drivers as below and check if it helps.

• Press Windows+X and go to device manager.
• Then expand keyboards and right click on the driver.
• Then click on uninstall and restart the computer.
• It will be reinstalled automatically and check if it helps.

Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

 

USB keyboards become unresponsive after unplugging/plugging three times

I have an odd problem with my USB keyboards on my Windows 10 machine. If I unplug them and plug them back in ~three times, they become unresponsive. The keyboards are still recognized by the machine and shows up under Devices, but won't send anything
when I type on them.

If I have multiple keyboards plugged in, the problem is contained within the one I unplugged/plugged back in, at least until I unplug and plug in previously unaffected keyboard (at which point they also stop working). Once the problem shows up, any
(previously not connected) keyboards I plug in are also affected. At all times, keyboards are recognized by Windows whenever they’re plugged in.

I've tried different USB ports, cables, removing items under keyboards in Device Manager to no avail. All the relevant drivers are up-to-date and power management for USB ports are disabled.

The only way to resolve it has been to reboot my machine.

Hello,

Thank you for writing to Microsoft Community forum.



To have a better clarity on the issue and guide you accordingly, respond to the questions listed below:

1. What is the make and model of the computer?
   
2. What is the make and model of the keyboard?
   

Meanwhile, I would suggest you to follow the below mentioned steps to resolve the issue.



Step 1: Run USB Troubleshooter.



Run the troubleshooter and diagnose Windows USB problems by following the

article which automatically fixes the USB issue.



Step 2: Create a Restore point and uninstall
Universal Serial Bus controllers.



Create a system restore point before make any major changes onto the computer to make sure that we do not mess up with it. You may go through the article on how to

create a system restore point.

After creating a restore point, go to device manager and uninstall the USB controllers.



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

• Right click on the Start menu and click on Device Manager.
  
• Expand Universal Serial Bus controllers (You might have to scroll down the list to find this item).
  
• Right-click the first USB controller under Universal Serial Bus controllers, and then click Uninstall to remove it.
  
• Repeat step 3 for each USB controller that is listed under Universal Serial Bus controllers.
  
• Restart the computer. After the computer starts, Windows will automatically scan for hardware changes and reinstall all the USB controllers that you uninstalled.
  

If you still have issues, go to the manufacturer’s website and update the chipset drivers.



Hope it helps.
