Jim, The USB 2.0 connector (there is only 1) on the motherboard is being used by the Corsair H100i CPU cooler. Had to add a PCIe card (and after adding the USB 2.0 port card the floppy diskette drive works perfect).
Didn't realize the USB-2 header was being used.
Lots of motherboards have two USB-2 headers.
In any event, it works... so the rest is moot.
