GA-Z77X-D3H Version 1.1 F14 4 of 6 USB 3.0 ports not working

[Brad]

The top two USB 3.0 ports work fine.  I attached a screen shot of the device manager.  I've tried updating the drivers, including manually using the "VIA USB 3.0 Driver" and the "Intel USB 3.0 Driver" driver from Gigabyte's website.  This did not work.  I'm not really sure what to do.  Any thoughts?  Thanks.

Surely someone has dealt with this type of problem before?  I have had no responses so far from Gigabyte.

As per pic,missing is LAN driver and Intel® INF Driver +  MEI Driver.

Thanks.  Are these drivers available at Gigabyte's website and will they also solve the USB 3.0 problem?  The motherboard did not include a CD as I expected.
