i think Hub is recomanded for computers which not have pci ports and new processors models (i5, i7)
i used a belkin pci card (2 usb ports) with my win setup or the TI didn't work at all.....
read the setup guide, they're talking about @ page 4
good luck
in my case the best (VC) setup is to use the ti with the analog outputs, so i use VC as an editor.....
