Install USB 3.0 Driver updates, chipset, and MEI drivers. Flashing BIOS won't hurt either.
Also consider using ASUS PC Probe, when installed it fixes a lot of device manager and driver http://www.techspot.com/downloads/265-asus-pc-probe.html
Thanks, Malignant. I installed ASUS PC Probe but found it to be useless for me. I thought it would automatically scan for new motherboard drivers like my MSI MoBo off my other system build.
Good advice, though. I'll flash the BIOS again and make sure I get all the latest updates for my motherboard and go from there.
