I bought a card reader and I want to install it but i'm not sure about the power connector. I am putting up two pictures. 1st question is in the one picture, is that a power connector or jumper pins, it looks like it says USB.
Second question is:
If that is the right connector, do I plug into the 5 pin or the 4 pin as the plug has 4 wires and one empty port and does it matter whitch way it plugs in.
Any help would be great. Oh. And yeah, its a bit dusty.
