Some back USB3 Ports not working

[Sem]

I have a problem my 2nd row of back usb3 ports they are not working at all devices connected to them are totally dead in and out of windows

according to the manual these are ports USB3_E56_E78

the 4 above them and the 2 below are working fine not sure why these are not i checked the bios and those ports are showing up as enabled

i am using a 5930k have SLI 780s and a X-Fi Titanium HD in the bottom red slot X8_4 i also have 2 SSDS and 3 HDDs connected so maybe the board disabled them because i have too many devices?

tried both 0802 and 0901 bios

Anyone tried the link? Does it work?
I already got a 2nd RVE replacement...just installed it and got the same issue which was the reason for replacement. Does not work. with any of my USB pen drives. Those do work on other USB ports (even with the USB3.1 PCIe card) though.
Are the two USB ports next to the ETH wired to another controller?
The LEDs go on when I insert the pen drive, it just goes undetected by the OS.

Hi,
I had the same problem and know it works with that firmware update.
