All USB Ports stopped working

[Accounts_BG]

I was changing over my wireless mouse and keyboard to another PC to use temporarily, plugged them back in after I had finished and now they will not work, tried all the USB ports - no luck. I have turned the PC off to try and reboot and hope it will accept them back but again nothing. I can't log in, can't access anymore than the start page. Please help....................

Thank you for posting on the HP Support Community.

Don't worry as I'll be glad to help, however, to provide an accurate resolution, I need a few more details:

• Did this happen after a recent window or software update?
• Have you made any hardware/software changes?

While you respond to that, let's try these steps: 

Perform the following steps to troubleshoot USB devices that are not working correctly:

• Power: If the USB device operates on battery power, make sure the batteries are correctly seated and are functional. If the USB device operates on external power, make sure all the power connections are secure and the power cord is connected to a power source.

• Test the USB connection: Sometimes, simply disconnecting and reconnecting the USB device to the computer can solve the problem:

  What happens when the device is connected?

  1. Disconnect all USB devices from the computer except a USB mouse and keyboard (if in use). This includes hubs, thumb drives, printers, and cameras.

  2. With all USB devices disconnected, do one of the following:

     • If you have a desktop computer, connect the device that is not working correctly to one of the USB ports on the back of the computer (the ports attached directly to the motherboard).

     • If you have a notebook computer, connect the device that is not working correctly to a USB port on the notebook. Do not use a USB port replicator (such as a docking station or USB hub).

  • The device works correctly: The problem is most likely related to power or poor overall system performance.

    NOTE: To prevent the USB device from failing in the future: Do not connect too many devices to the computer; wait 5 seconds after connecting a device before using it; use powered hubs to connect other devices; and do not attach USB devices when the system is busy (running slower than normal).

  • The device does not work: Leave the device connected and continue to the next step.

1. Installing USB manufacturer software: Some USB devices require manufacturer software be installed before the USB device will work.

   The device should now work correctly. If problems persist, continue to the next step.

   • If the USB device came with software, and it was not previously installed, install the software now, following the manufacturer instructions.

   • After installing manufacturer software, reconnect the USB device that was having problems.

2. Microsoft easy fix solutions: Microsoft provides a web-based automatic diagnostic and repair application. Go to the How to use Microsoft easy fix solutions webpage (in English) and select the troubleshooter that most closely matches your issue. Then follow the on-screen instructions. If the device still does not work, go to the next step.

3. Windows Update: Running Windows Update checks for operating system updates required for your computer. Go to Windows Update (in English) and follow the on-screen steps to check for updates, and opt-in on all recommended and optional driver updates. If the device still does not work, go to the next step.

4. Microsoft System Restore: If the USB device was previously working, then subsequently became unusable, try Microsoft System Restore to go back to a time prior to when the device failed. Refer to Using Microsoft System Restore (Windows 10, 😎 for more information. If the device still does not work, 

Hope this helps! Keep me posted for further assistance.
