Hi. I mahve this issue for a K30 Keyboard, I tried these steps and worked perfectly, but now i have an issue, the keyboard is detected as a K40, and all the keys are writing different stuff, i wonder if this is because of the K40 Firmware on my K30, I don't know if the K30 Firmware update exist, I can't Find it, does anyone have access to it? Thanks a lot
