Can you try getting the dmesg.

You can also disable USB enumeration setting these:

hw.usb.disable_enumeration: 0
dev.uhub.2.disable_enumeration: 0
dev.uhub.1.disable_enumeration: 0
dev.uhub.0.disable_enumeration: 0

Are you sure you loaded all drivers, like XHCI, EHCI, OHCI, UHCI ? DOes 
the BIOS offer any USB options?
