Not just these
The difficulty occurs with any xhci controller, not just these. It gets tricky if the install is done from a usb3.x port. As long as you have a USB2 port you are fine. I'm writing this on a lappy with sandy bridge and a renesas xhci usb3 controller on one port. I can't install win 7 through that either. Thin lappy with a single USB3 port and nowt else = bad idea. That's all they'll offer then. Corporate grade e.g Dell Latitude will be OK. Consumer? Just be grateful and shut it.
