Processor:Intel Core i5 3475S
OS:Windows 7 x64 SP1
USB 3.0 Driver version:v126.96.36.199
USB 3.0 ports doesn't recognize USB 3.0 devices (Thumb Drive, Portable HDD), but USB 2.0 works good on USB 3.0 ports.
I have tried USB 3.0 Driver from v1.0.5 to v1.0.9, don't work both.
Hello Ryanliue, since the issue you are experiencing is specific with USB 3.0, I would recommend you installing BIOS version 0046 because it fixed an issue with USB 3.0 devices.
You would need to use the recovery method. http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm http://www.intel.com/support/motherboards/desktop/sb/CS-023360.htm
Please test a 3.0 device after that. Finally, update the BIOS to latest version.
You can also try testing the system out of the chassis
