I bought some time ago Keyrah V3. I tried connect to computer with window 11 and to RPI3 with BMC64. I also used two diferent commodore 64 keyboard and two usb cables. Unfortunately it not working. Keyboard isn't discovered on windows and on BMC64. Here is photo how is connected the keyboard https://ibb.co/YkFX5jD
I need some advice how to check it work or not.
