Double check connections and try again, or use -F to override
When I try to program my arduino pro mini with this USBasp all works fine. My arduino software is 1.6.5, the tiny hardware for arduino is "arduino-tiny-0150-0020". I tried 3 attiny85. I used eigher attiny@1MHZ 8MHZ and 16MhZ.
What I can test? Do you need more info to help? See also my attachment.
Try checking your wiring again. I get the same message when I have my 6 pin ISP plug connected backwards. You can check your vcc , ground and reset with a led tied to a resistor or use a DVM. My reset reads around 4 volts using a cheap DVM. Using a led with a 220 ohm resistor I get a bright light between 5V and ground and a dimmer light between ground and reset.
You may have to get some help from one of the guys who know what they are doing.
again I used my digital voltmeter to check the wiring. Connected to USB I get 3.28 V between vcc and gnd. And I checked also MISO MOSI SCK and RESET. There is no short circuit and all wires are connected correctly.
When I switch the USBasp to 5V I get 4.80 V. But both don't work.
I also own an USB FTDI232. Maybe I can try this? But I can't find the wiring plan for this."
Yesterday I wired up the circuit from this link and was able to load bootloader @8Mhz and then loaded a Morse code sketch I copied from the forum. As long as I left the 10K resistor in the circuit everything worked. When I pulled it out of the circuit, I got the same error message as you are getting .
