I believe it’s a driver issue. However, I see conflicting information and various drivers for this product. I’m running Windows 7 pro 64 bit. I’ve tried the drivers from the Sparkfun product page and from the Adafruit page. However, when I try the test command ’ avrdude -c usbtiny -p m8 ’ it tells me that USBTiny could not be found Yes, it’s plugged in with 2 blue lights and the red light lit). Could someone tell me which drivers I should be using and the correct method for installing them?
Thanks
