So the USB controller model TS-PDU3 comes with an NEC chipset.
NEC is called RENESAS now.
You can see the lineup at

I think it's the µPD720200, but I couldn't find a way to download drivers for it from their site.

Download the transcend driver and install.
filename : RENESAS-USB3-Host-Driver-20320-setup.exe
It will install as
date : 12/10/2010
version : 2.0.32.0
Then go to intel's website and download their updated drivers

filename : USB3.0_allOS_2.1.28.0_PV.exe
EDIT: updated file same link is USB3.0_allOS_2.1.28.1_PV.exe
Run and it will automatically update to
date : 10/25/2011
version : 2.1.28.0
Maybe there are newer drivers but this fixes the issues with recognizing some USB drives.
This was all tested on Windows 7 x64.
