i need to flash an USB Serial Light Adapter. I know it uses an ATMEGA8U2 and i learned about FLIP and entering the controller in DFU mode. Tre problem is that i cannot find the right firmware to flash the 8U2. If i use the Arduino-usbserial-uno.hex file , when i plug in the board it is recognized as an Arduino Uno instead of an USB Serial Light Adapter so.. where can i find the right firmware?
Thank you all
