The media card reader should have a 9 pin connector.  You plug that to an internal USB 2 header on motherboard.
Hello all, I have just upgraded from a 7020 MT to a 9020 MT. It came with an optical drive and I want to install a 19 in 1 media card reader. The reader that I purchased has an attached cable with a small 5 pin connector on it. My question is where do I plug this in on the motherboard? Thanks for any and all help.
