[SOLVED] Crosshair Hero VII Wifi USB 3.0 header issue

[mickrc3]

I have the motherboard in question installed in a Thermaltake Core X9 case with 4 front USB 3.0. The motherboard has one USB 3.0 header and one USB 3.1 gen2 header. I've tried the gen2 to 3.0 converter cable and it results in one non-working front USB 3.0 and one that detects devices but then crashes the connection with corrupt device error messages. But the USB device works fine on the other pair of 3.0 slots connected to the 3.0 header. So I bought a PCIE USB card that had a USB 3.0 header and installed it in one of my PCIE x1 slots. But after installing it the system will not boot all the way into Windows, it gets to loading windows and then either starts over or says system is corrupted and goes to repair screen, but even with a brand new boot drive and nothing on it, it cycles through the repair over and over. Thought it was a bad PCIE card so I bought a different one, same thing happens with it. So I am wondering if anyone else has been able to get all four USB 3.0 to work short of buying a new motherboard with 2 USB 3.0 headers?

You forgot to mention the make and model of your PSU. Are you on the latest BIOS update for your motherboard? Also, the USB 3.1 gen 2 connector should be sued in tandem with a type-c front panel port, avoiding any adapters.

Which PCIe slot are you populating for your USB card?

P/S is a Antec HCG850 Gold

MB BIOS update is behind a few versions - I didn't notice that a lot of updates came out after July last year.

My case does not have a front panel type-c port, just the 4 USB 3.0 type-a. I have a front panel fan controller/USB 2.0 mounted in my bottom 5.25in bay. I am ordering a Gen2 cable (motherboard header to single type-c port) and will mod the case to use the port on the front or will leave it on the slot and put it in the rear. My case is accessible on three sides so I can live with the type-c on the back if necessary.

USB cards have been tried in PCEX1_1, PCEX1_2, and PCIEX4_3. I want this solely to get all four front USB 3.0 ports working.

An update. After a lot of searching I found out that the Gen2 motherboard header to USB 3.0 header cable does correctly make one front panel port work - but only with USB 3.0 devices - it is not backwards compatible. After looking at the pinouts on the headers I can see that is the best I can get going that way. So I am going to purchase a Sabrent USB 3.0 header hub (HB-INTR) to get all four front panel USB 3.0 working and backward compatible. Because I found through the reviews that the Sabrent hub has a power leak issue but otherwise works I am going to power it with an external brick (from a kit to run a SATA drive outside of a case) instead of the supplied SATA power splitter. Still wonder why any PCIE USB 3.0 card with internal header prevents the computer from working. Will post results of the hub experiment.

Okay, hub arrived today and was a quick install. Used a water cooling tube pass-through on the rear of the case to run in the power line for the Sabrent hub. All 4 front USB 3.0 run as USB 3.0 and all support USB 2.0 and older now. The USB 3.1 Gen2 header is now connected to a rear slot port to the left of any motherboard PCIE slots. As the Sabrent hub provides another USB 3.0 header I plan to replace my current front panel with fan controllers and 2 USB 2.0 with a unit that has USB 3.0 and USB 3 card readers in it. I now use RGB case fans and fan speed is adjusted though their controller and remote.
