Here's my crude attempt in Ascii art. Bear with me....
Imagine the end of the USB connector (where it connects to the motherboard).
|[] [] [] [] []| Red, White, Green, Black, Black (or nothing)
|[] [] [] [] []| Black (or nothing), Black, Green, White, Red
Most USB connectors have 4 wires, some have 5. If this doesn't work, try switching around the green and white wires. I'm not at my MSI computer, so I can't be 100% sure...
