YE-8v08 reader drive install problem

Question

I have installed it (poor instructions) but what can I do wrong? The cable from the mother board only goes on one way (it has a tab in the middle) and same for the back of the drive. Here is my question. The drive comes with 2 cables: one is USB miniB to the 4pin colored cable. It shows a picture for that, although all you are doing is jumping from one spot on the drive to another...... no problem, then there is a USB to USB mini cable noplace to plug in. How does this thing get it's power? there are no more places to plug any thing into???thankstravis
