Can't boot with USB card in PCI x1 ports

[genegold]

I just received a PCIE USB card designed for audio (JCAT | JPLAY - hi-end audio player for Windows) and tried it in two different PCIE x1 ports but the computer won't boot; i.e., it's stops at the mobo screen (there was power to the card). Two obvious possibilities: bad card or mobo problems. I've never used the PCIE x1 slots - there are three - but I've got a GPU in the PCIE x16 slot and a different USB card in a PCI slot that work fine. When I pulled the new card, the computer booted right up. Any thoughts? I'm contacting the card maker, but thought it worth posing here as well just in case. Is there any way to test or check those ports w/o other PCIEx1 devices? Thanks,

UPDATE: I've also tried the x8 and x16 ports w/o luck. According to the developer, someone else with this problem turned on USB fast boot option, but not sure what that is. I tried enabling Intel Rapid Start Technology in BIOS, but no luck (have SSD). Btw, I'm using the UEFI beta BIOS, the screens for which are in the GA-Z77X-UD3H board's manual. The developer also says the card is based on the latest NEC chipset and some boards are having problems with it. Others report Haswell-based boards have no problem. Win 8.1 Pro x64.

Re: Can't boot with USB card in PCI x1 ports

Could this be a BIOS problem, i.e., might the latest (UEFI) BIOS need updating for the NEC uDP720201 controller, which the JCAT uses. Another card that works in a PCI slot uses a uDP720102GC NEC controller (201 vs. 102).
