System stalls when booting (stops after the initial POST screen is displayed) if the Chieftec Card Reader USB 3.0 CRD-601-U3 is connected through the MB’s internal USB 3.0 header. If you start the system with the reader disconnected and plug it after the OS is fully loaded, it is recognized and it works as expected/designed. The CRD-601-U3 offers dual USB 3.0 and USB 2.0 connectivity and if attached through the internal USB 2.0 header, no stalling occurs. The system boots up normally.

Hi
My initial thought would be that the wiring may not be correct on the card reader. It wouldn't be the first time that I have come across it.

Otherwise you have a manufacture problem with card reader i have known different ones to cause problems all the way back to vista days.
Like when i added my ssd drive if i had my card reader attached it would hang in windows setup. With it unattached it went right thru and now works plugged into a usb 2.0 inside port.

Wiring is sperfectly all right. Otherwise the reader wouldn't be functional at all. I made it clear in the initial post that if you start the system with the reader disconnected and plug it after the OS is fully loaded, it is recognized and it works as expected/designed.
I contacted the local Gigabyte tech support and was adviced to return my MB to a retailer. Since waiting three weeks didn't seem sexy at all, I bought a new MB: AsRock 970 Extreme4. The reader works like a charm - no problems booting and overall booting time seems much faster plus no problem with entering BIOS (it was horrible with GA-970A-UD3 ). As you can clearly see, this is obviously some issue with Gigabyte BIOS programming or/and a defective board.

Could be either or first troubleshooting tip is check all things you can first ie wiring , connectors and so forth then get a known good part and try it. Glad you got it sorted though.
