Step 4The End
Well, I know that I didn't add much new information or near as many pics as I wanted, due to the aforementioned card reader malfunction. But at least I did some actual testing and uncovered one reason that some supplies may not require loading of the 5V output... So probe the resistance between 5V rail and ground on your supply. It may be good-to-go right out of the box, like mine was. And if you really wanna know what's going on, pull out the multimeter and do some testing. There' s no substitute for checking and knowing things for yourself.
