I have installed the drivers of STLink -v3 and Virtual COM. After connecting the computer with a type-a to micro-b usb cube, it can't be found by the computer.

Make sure you're using the right USB connector on the board. Try a different cable. Try a different USB port. Reboot.

Make sure cable is viable, charging cables won't work.

Silly mistake. I was tried three different usb cabels and they all were charging only cabel by coincidence. So I bought a new cabel that could transmit data then the problem got solved.
