Foxconn PRODUCT : Motherboard : Details

Clearly stated 10 x USB 2, 4 rear panel, 3 x 2-port internal headers on the motherboard (seems excessive, but there).
The only way to get USB 3 would be to install a USB 3 PCIe card - if you have a slot free and usable. The board supports PCIe v2, so you would get nearly the full benefit of USB 3, assuming that you can use the PCIe X1 slot (500MB/s).
Unless your case supports USB 3 already, you could either go for a 4 x rear port USB card, or a 2 x rear / 2 x internal and buy a USB front panel to connect to the internal header.
I'm knowledgeable about all this having very recently done just that.
It was very much end of an era, as I removed the floppy disk drive to fit the 2 x USB 3 front panel!
