None of the current Intel chipsets "natively" support USB3.0, but that only limits you from booting off USB 3.0 or accessing in the BIOS. Its no big deal, and "I" couldn't care less about it.
All you need to do, same as ANY Intel MOBO is to add a secondary USB 3.0 chipset e.g. NEC and others. The LGA 1155 up to the current Z68 have the same 'problem'.
