Replace ATMEGA328P-AU chips

Sorry about that. I thought I had most models of USbasp and this one I don't have. :slight_smile:

I don't know what firmware you loaded , but I have had real good luck with this one. Has Auto SCK.

""usbasp-v1.06-alpha-2016-04-17-atmega8.hex" from petervh/bperrybap solves all these issues. myself and friends been using it for couple months now. big improvement. more info and other versions: https://github.com/bperrybap/usbasp/tree/1.06-alpha."

I can get the same error with nothing connected to the Usbasp. I guess it is possible the chips are dead, but a simple wiring error will cause the same thing.

Pin 4 and 6 on some Usbasp are TXD and RXD. I notice you might have your Gnd lead on 4.
