I bought to program Atmega328P on non-standard boards. Although I have read and experienced that you have to burn the bootloader to set the fuses correctly when using an external crystal, I got the error message "I opens Blink - File -> Examples -> Basics -> Blink then Sketch -> Load with Programmer (I saw the delay was a few seconds when it should have been 1 since it was using the internal clock and not the 16MHz crystal I installed. At this point I was able to "Tools -> "Burn Uploader" Had to send the program to the board first) using Sketch -> Upload with Programmer, after that I re-burned the Blink sketch and the timing was correct. About using Zadig and updating the firmware on libusbK Zadig is a Windows software and I wanted to avoid it, it seems to be working fine with a warning.
