Hi Daniele, Sorry for the delayed response. We would like to know whether the issue has been resolved or not.
If the issue still persists, then I would suggest you to uninstall and re-install the drivers in compatibility mode and check if that helps. Here is the steps: • Go to your manufacturer’s website and download the Driver setup file for your computer. • Press Windows Key + R on your desktop screen to go to run box. • Type devmgmt.msc and hit Enter. • Look fir the Drivers, expand, then right click and select Uninstall.
• If you are prompted to Confirm, then Confirm. • Go to the location where you had saved your downloaded setup files of the drivers and right click, then select Properties. • Select Compatibility Tab. • Place a check mark next to Run this program in Compatibility mode and select the operating system accordingly from the drop down list. • Let the driver to install and then check the functionality. Let us know if the issue still persists and we'll be happy to help you.
