Generic NEC USB3.0 PCIe Installation problems

Hey everyone, I'm having a heck of a time trying to install a NEC USB3.0 PCIe card. I'm running Mountain Lion.

Here's the card I purchased (screenshot): http://i9.photobucket.com/albums/a98...-USB30NEC.jpeg
I dont have the molex power adapter connected, from what I've read it's not required on a Mac Pro. Is this true?

The device I'm trying to use a WD MyBook 2TB USB3.0
Works fine in my USB2.0 ports.

I've tried a few .kext files but no luck. The furthest I've gotten was when following this tutorial: http://forums.macrumors.com/showthread.php?t=1238494 The only .kext that shows up in the USB System Information is the old one from this thread. Newer .kext dont seem to work. By the way I had to use Kext Wizard because Kext Helper wouldnt download.

Here's a screen shot of my System Info, the WD drive is plugged in but isnt working.
And AHCI Controller is my ASM1061 eSata/Sata card.

I would love to try another USB3.0 device but I dont have one at the moment.
Any suggestions is super appreciated.
