The device uses the standard cp210x driver, I found some program
But in the end, I still did not understand what it gives me and how I can get data from the device when connected

Answer 1

The device has its own UART communication protocol. To merge the necessary data, you need to know it. Or use existing programs to work with the device that can do this.
