USBtiny (AVR Pocket programmer) "Problem Uploading to board"


Apologies in advance if this is an FAQ (if so, where?)

I recently upgraded to Arduino 1.6.6 on a Win7 64bit PC. I’m unable to program the Blinky example sketch to an Arduino UNO R3 board using the AVR Pocket Programmer (from Sparkfun Electronics)

The drivers are the latest:
Driver provider libusb-win32
Driver Date: 1/15/2013
Driver Version:
Digital Signer: Adafruit Industries

I discovered that I can program the blinky hex file to the same UNO board using AVRDude from a CMD window.

Avrdude –c usbtiny –patmega328p –U flash:w:Blinky_01.ino.hex

I think the hardware is correct, should I expect to program this hardware directly from the Arduino IDE? ( Tools > Board = Arduino/Genuino UNO and Tools > Programmer = USBtinyISP Note: “Port” option is grayed out)

I get the following error message from the Arduino IDE

avrdude done. Thank you.

I’m returning to this project after a long absence, what did I forget to do…?

Thanks In Advance!
