HP Convertible x360 11-ab0XX
Microsoft Windows 10 (64-bit)

Yesterday Windows (without asking me) did upgrade and rebooted automatically. Just after that the right USB 2.0 port stopped working - I couldn't use it for external keyboard or mouse. The left USB 2.0 and USB 3.0 ports continued to work. 

I executed built-in PC diags test for this USB port. It showed Ok if I connected flash-drive, and it showed error "m0aax0-8nl8q0-xd7uqj-8d4p03" if I connected a keyboard or a mouse. The same devices connected to another USB port worked normaly.

After that I discarded the latest updates of Windows and the right USB 2.0 port started working with a keyboard and a mouse properly.

It's very strange to me.
