I double checked today as the manual shows on page 3. I have a GA-990FXA-UD3 rev. 1.0. I have also tried to solve the problem with an updated to the bios to version F9, but the problem is still there.
I used windows 7 64bit business for almost an year. I tried re-installing it after a complete format but the error was there again.
Now i'm using windows 8 64bit professional and the error is still here.
Yes the drivers i used for usb3.0 are from the Gigabyte website and they are for my motherboard model and revision.
The usb HDDs or memory sticks work great on the USB2.0 ports, they sometimes hang in the usb3.0 ports, only the Wi-fi adapter fails on both usb 2.0 and 3.0 as i said in my previous post.
I have tried today what you have asked, after the new user account has been created and a restart, after i log into the new account and start web browsing the usb port of the wifi adapter fails again.
More details about my system:
