I suppose they actually mean "USB 3.0 with support for PCI Express Gen 2". That means that they need the full speed of USB 3.0 spec, which is not supported by PCI Express 1.0.
Ah! That might explain the problems I experienced with the old render boxes. I
think the motherboards have both types of PCI slots but the faster slot is being used by a 'Kinect-compliant' graphics card I installed, and the slower PCI slot is being used by the USB 3.0 card. I'm not certain about this but I don't think I'm going to be able to have both cards on faster slots in these computers. Maybe I can swap their positions of the cards but I suspect that won't work either...I can't check right now but I think interfaces are different. (Originally, these computers were never meant to be used for anything but rendering so, except for the processors and RAM, they're pretty bare bones. Oh, well.)
I'm not hopeful but I'll see if I can dig up the specs on these computers later just to be sure. For the time being though, I'll focus on recording with the gear I've got working now. :)
