I have compared them and everything looks to match exactly. All plugs appear
to be where they're supposed to be. There are no jumpers involved. There are
also no BIOS option for turning on or off any hubs or Enhanced USB switches.

The first six USB plugs are hardwired to the MB and the added "D"-bracket,
which came with this MB, is USB2 capable (according to the manual and print
on the bracket), and is plugged into the only place it can be.

Thanks for your time and help.
