Answer 1

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.

This happens because of an interference between the USB mass storage driver (brut) and ASUS USB charger plus (newer versions), otherwise ASUS power4gear program. Uninstall the drivers and the programs, it will work like a charm. Cheers! Viscol.
