I have a newer version of the Meggy Jr. RGB and whilst trying to learn to program it, I tried to upload an example to Meggy. It did not detect the usb used in order to upload programs onto the Meggy Jr. I have looked in Tools>Serial Ports and so far the Arduino has never detected my usb. I was curious why this might be occurring and how I might be able to fix it. I was using the TTL cord that I ordered from Evil Mad Scientist Laboratories by the way in case that helps.
