I have switched between keyboard and mouse (2 usb2 black) and now the mouse seems to be recognized fine. Could someone explain why switching worked?

There are 2 separate usb controllers. usb2 black ports and usb3 blue ports. Windows by default will have standard drivers for usb2 however because usb3 ports are controlled by another controller windows might not have the drivers for it so it needs to be installed.
As @'Plec suggested check in device manager > Other Devices > Universal serial bus controller for any yellow warning symbols next to it, if you do have it, download below drivers and try installing them as they are originally for windows 7 but should work for windows 10

Alternatively you can do full windows update which might download missing updates and drivers.
