Waiting for a reply back from manufacturer, but I anticipate the answer will be no.
As most integrated USB ports on cases I've owned had a removable bit of circuit board with cables connecting to motherboard headers. I thought premium case manufacturers might offer updates if there was a market for USB 2.0/Firewire 400 to USB 3.0/Firewire 800 replacements. Has anyone seen a company offer this?
Edit: I just thought, is there any difference between the USB ports? If not then can you connect a USB 2 port to a USB 3 header and it will function as a USB 3 port?
