Setup Installation :: Change Windows To Go USB Port While In Use

How do I change the USB port that Windows to Go listens the drive while in use?

I have this computer, with an Asus P8H61-LE Motherboard. As you expect, it doesn't pack USB 3.0 ports. But it does come with some nifty PCI-E x1 slots, so I've bought a random USB 3.0 PCI-E card, with 40 pin for front panel.
Works amazingly. Fast and beautiful, exactly what I've expected. BUT, it doesn't have its own BIOS or something, so my UEFI BIOS cannot boot from devices connected to it. In fact, it doesn't even detect anything there until I boot up to the O.S.!

And I have this Windows to Go Setup. Works like a charm on USB 2.0, but sometimes I feel the bottleneck, and wouldn't hurt using my only USB 3.0 device on those USB 3.0 ports, eh? I've tried disconnecting and reconnecting it on USB 3.0, but WTG just ignores it as if it weren't there. Even when I connect to a different USB 2.0 port, it doesn't detect.

This USB port remapping would serve for other uses too. Once, I've connected my drive to a client's computer, for repairs. But it took longer than I expected, and I had it connected on the front USB. I needed to connect other thumb and external hard drives and had to use the rear USB ports for this, because WTG didn't detect anywhere else.
