I'm running IDE 1.6.7 on Win7 x64. I'm trying to upload the example Blink sketch over USB to an Arduino Micro and getting a "programmer is not responding" error (see below). In the IDE, Board is Arduino/Genuino Micro, Port is COM5, and Programmer is USBTinyISp (the output says it's using avr109 as the programmer, but that's not one of the choices in the Programmer list). I've updated the Arduino driver in Windows Device Manager. Any suggestions? Thanks for your help.
