However, the official Atmel AVR MKII is not able to provide power to the target board. Since the pocket AVR programmer can provide 5V power to the target AVR with the switch flipped to the Power Target position, a USB cable is not needed for the RedBoard.
You also might notice that there is not a USB cable connected to one of the RedBoards. The AVR MKII's cable has MISO connected closer toward the outside of the cable. As shown in the image below with MISO highlighted by a white dot, the pocket AVR programmer's cable has MISO connected closer toward the inside of the cable.
Heads up! There is a subtle difference in the orientation of the 2x5 to 2x3 AVR programming cable compared to other 2x3 cables that are attached to official Atmel programmers.
