ATTiny85 upload error

I'm getting "An error occurred while uploading the sketch" when uploading a simple sketch to an ATTiny85 connected to my pc through a Sparkfun Tiny Programmer. The compilation goes through fine but there is no extra error info why this happens. Any clues?

int blinkPin = 0;

void setup()
{
  pinMode(blinkPin, OUTPUT);
}

void loop()
{
  digitalWrite(blinkPin, HIGH);
  delay(500);
  digitalWrite(blinkPin, LOW);
  delay(500);
}

Turn on verbose output for upload and post the results here using [code][/code] tags.

Here's the code. In the Forum I found a guy who solved the problem by changing the programmer from AVRISP mkII to ArduinoISP but it gave me another error. I also tried to change to USBTinyISP which gave some errors but did blink the LED on the programmer.

Error code with AVRISP mkII:

Error code with USBTinyISP:
(snip)

It looks like the upload process has completed successfully there, what makes you think there has been an error?

I just saw a possible error in the listing:

" Description : USBtiny simple USB programmer, Overview | USBtinyISP | Adafruit Learning System
avrdude: programmer operation not supported"

It doesn't say what operation it is but if it's just a comment I'm happy that it works now.

Given the rest of the message I'd say that it has written correctly.
Incidentally, if you look at the Sparkfun hookup guide you'll see that USBTinyISP is the correct programmer selection to use.

I read it again and I noticed that. Thanks.
