DZ77RE-75K USB 3.0 FP interface problem

Mobo: DZ77RE-75K

CPU: Core i7 3770S

Problem:

1. If I connect the "Official" USB 3.0 front panel to this mobo, then only one USB 3.0 on the FP work.

2. If I connect the "Thirdparty" USB 3.0 front panel, then all of USB 3.0 on the FP does'nt work.

3. If I connect a mobile HDD or a USB stick to "BAD" USB 3.0 on the FP, device lights on, but does'nt work.

Anybody tell me what's the problem?

So I hear you saying that when you connect the in-box front panel USB 3.0 and a third party front panel USB 3.0 only the in-box ones work. Also, if you plug only the third party one in, it doesn't work.

Based on that it sounds like the third party device is either faulty, or missing drivers. What device is it by the way?

Drivers are OK.

Third party FP don't need driver.

Are you able to test the third party USB ports in another system?

It has been discussed before, i don't have time to find the threads. It is something related to the 10th pin on the motherboard USB3 header. For DZ77GA-70K this was solved by a BIOS update, now my Chassis FP USB3 port works but i get power surge messages in Windows. Intel USB3 bracket works fine, both ports.
