I'm actually trying to troubleshoot this for my sister's u47a right now.

It appears that something from ASUS's LiveUpdate software, possibly (specifically) the Charger+ utility, interferes with the USB 3.0 driver operation.

We're reverting to a restore point via Windows Backup/Restore right now.

Others have reported success by downloading the updated Charger+ utility from ASUS's site: http://support.asus.com/Download.aspx?SLanguage=en&p=3&s=111&m=USB%20Charger&os=30&ft=14&f_name=USBChargerPlus_Win7_64_Z211.zip#USBChargerP lus_Win7_64_Z211.zip

Hope this helps. Otherwise, I'll update with any success we have.
