hello. I used the following chip.
STM32F103C6

I did it like the video above.

1. The process is complete, but the 'COM' and 'Port' drivers are not installed.
2. Even if you proceed with the update file, 'COM' is not created.

Why?

It's an USB bootloader, but it does not use COM port for firmware upload. COM port is used only to reset board and you need to flash firmware with USB Serial enabled to see COM port.

Also, it's an old bootloader, HID bootloader is a better option: https://github.com/Serasidis/STM32_HID_Bootloader/
