I followed the video on How To Install WHID Injector Software on WINDOWS - YouTube (How to install WHID Injector Software in Windows).
In the video, there are three windows open in Arduino IDE: ESP_Programmer, ESP_Sketch and Arduino_Skets.
When I open Arduino IDE, I only get one window, called Sketch_jun12a.
I managed to install the ESP8266 board, but at the moment, I ran the upload, my WHID Cactus was unusable. Even the ResetDefaultConfic: from the SerialMonitor does not work.
However, it seems Arduino IDE is still having abilities to “talk” to the USB device. How do I revive it?
