stm8s serial communication cannot detect the port [Copy link]

Please help, what is the reason, is there a missing driver or something else?

There is a problem with the communication port in the device manager. Is this the reason?

You need to install the serial port driver, CH340

Installed, still not working

Go to the official website to download the driver again. The debug port and serial port are a composite USB device, so the driver must be installed completely.

Insert a serial port module to see if it can be recognized.
