Unknow device USB when connect axiom 49

I have bought new motherboard Asus Z97 AR and when i connect my keyboard i see message "Unknow Device USB." Probabbly one of your devices is broken. Fix it or replace by other device.. (Great tip) I also downloaded drivers from M-Audio site and it did not changed. In devices mannager i see my keybord in other devices marked as unknow with big yellow sign. Is it possible to the motherboard is broken?
