Wemos D1 Mini (ESP8266) control with USB

I have a Wemos D1 Mini (ESP8266), flashed with WLED and I want to create an application like .exe and have control on turning it on/off and choose colors. Does anyone have any idea how I can do without to connect on wifi and just do everything via USB?

To control the WLED firmware over USB, you would use the firmware's ability to be controlled over a serial connection. It looks like you would open the virtual serial port that appears when you plug in the device, at a speed of 115200, and then you take the same JSON that you would POST to /json/state for controlling it over WiFi, and instead send it over the serial connection, and get your responses back over the serial connection.

You could also implement the TPM2 protocol, or the Adalight protocol (which doesn't really seem to be documented except in code), as those are also supposed to be supported.

If you want to do all this in C++ on Windows, you might start by reading the (very old) Windows tutorials for Win32 API serial port programming. If you only want to target Win10 or newer, you could learn C++/WinRT and then use the new WinRT serial APIs. Or you could consult the answers to this question about serial programming on Windows.
