Hello,
I have an Acer All-in-one (BIOS version R01-A1) that was working just fine under Windows 10 v1809. I have made several attempts at upgrading to 1903 without success. One of them was performed using an ISO disk downloaded with media creation tool.
As I was upgrading to 1903, the mouse and the keyboard were operating normally but as soon as the process ended, I am not able to use either of them. I have switched them to other USB ports from USB 2.0 to USB 3.0 and back to USB 2.0
without any effect.
I have made an attempt at booting in safe mode but the mouse and the keyboard are not available.
I have managed to get back to the 1809 version of Windows 10 and as soon as it was available, the mouse and the keyboard were back. When I go to the BIOS, the mouse and the keyboard are functioning well. The same with booting from the
ISO DVD in repair mode.
I have checked the Windows 1903 page for reported problems and I haven't found anything in line with my problem. I have checked the driver page from Acer and found nothing new. I have not found anything on the web matching with my situation.
So the question remains: how come upgrading from 1809 to 1903 causes such a problem for something as basic as USB ports?
Hope that someone can help me in resolving this major issue.
Awaiting feedback.
Regards
