But the rollback option is now avaiable so you need to do the steps I mentioned you in this post.Īny one had this issue? This is affecting all HP computers with USB HP Optical Mouse model MOFYUO of our client, so we believe this is affecting a lot more machines and users wordwide. After that, click OK and wait a few seconds, you will see that Windows will recognize and install "HP Optical Mouse", after that is complete you will see that you can't use the mouse yet. You need to check the option "Remove software related to this driver". You achieve that going through Device Manager.
If you are not able to rollback the driver, first you need to fully Uninstall "HP USB-C to DisplayPort Adapter". We are under investigation but this looks to be an issue with a particular Windows update. We need to repeat these steps for each computer and each USB port of that computer. After that we get a warning message and we confirm that we want to rollback the driver as follows.Īfter that the USB HP Optical Mouse mouse instantly starts working on that particular USB port, you will see that it dissapeared from the Device Manager, even if you restart or if you "Scan for hardware changes": We can solve the problem, opening the Properties > Driver and selecting " Rollback driver" Since we can't manage the computer using the mouse we need to solve this using the keyboard, accessing through Remote Desktop or with other mouse device (PS/2 or USB). So open the Device Manager and you will see that Windows is identifying the HP Optical Mouse as " HP USB-C to DisplayPort Adapter" which is causing the issue. If you change the optical mouse with any other mouse (PS/2 or USB) it works, but with the USB HP Optical Mouse it doesn't! The mouse just stops responding and if you reconnect the mouse to other USB ports, the issue remains.
This is related with recent Windows Drivers and we are trying to identify which update is causing the issue. Since today our client are experiencing a strange issue which affects all their HP EliteDesk, HP Compaq DC7900 SFF computers with HP Optical Mouse Model MOFYUO, P/N 672652-001 and Windows 8.1 Professional 圆4.
