Just completed a refurb/upgrade and the front panel USB 3.0 ports are not working.
Old - i5 3330 CPU, OD, 1 TB Seagate HHD, 6 GB RAM (4+2), Windows 8.1 OS
New - ASUS P8H77-V MoBo, Corsair CX600M PSU, Zalman Z9 u3 case

Instead of running the USB 3.0 front panel cables on the new case to the back port on the MoBo, I reused the 3.0 front panel ports/cables from the old case with 3.0 MoBo header 20 pin as an adapter to the 3.0 header on the new board. Seems like it should work but I get nothing when plugging into the front panel 3.0 ports on the new case. The 2.0 ports are fine.

Thanks
