Mouse and other USB do not work + beginner’s question

[apparatus]

@Justluck

I have a few problems that I hope to find an answer here. The system does not detect my usb mouse. There were no errors during the installation of the system. I have sys-usb installed. The mouse is on USB. The system does not see any usb devices.
Can I ask for help on how to solve this problem?

Do you see this window appear when you disconnect and connect back your mouse cable?
