USB 3 PCI-E expansion card

[danwellman]

I've got an ASUS P6T Deluxe v2 board (https://www.asus.com/uk/Motherboards/P6T_Deluxe_V2) and I just bought an Anker USB 3.0 PCI-E expansion card (http://www.ianker.com/product/68UPPCIE-2S20PU). I'm running Windows 8.1

The manual for the expansion card says the card will work in any PCI-E X1 / X16 slot

I've got a spare PCI-E x4 slot and 2 spare PCI-E x16 slots. I tried the expansion card in both the X4 and one of the X16 slots, but I can't get it to recognise a USB 2 flash drive.

The drivers installed fine and in device manager I see an entry for VIA USB 3.0 eXtensible Host Controller (which says the device is installed and working correctly)

I've connected the 4 pin molex power connector.

Any ideas what could be wrong? Is there some BIOS setting I need to enable or something?

Are you able to try it in a different PC?

Unfortunately not. Not easily in any case - I only have one desktop.

Is there a possibility that the power is not enough? I've got the molex coming from one of the tiny 3 pin fan sockets (to make the internal wiring a little easier), is it worth trying a different power connector from the PSU? Although I would have thought something like a flash drive should work...

Or does it sound like the card itself may be faulty? It is brand new

You need to be using a PSU connection. I doubt the motherboard is supplying the correct voltage.

I tried this (before I saw your second answer) just to rule it out, and also tried the other spare PCI-E x16 slot, just on the off-chance. It didn't make a difference, the problem was the same. I'm tempted to believe the card was DOA so I've already arranged a return.

Probably going to go for this one instead: http://www.amazon.co.uk/express-controller-external-internal-interface/dp/B00NXTQBOY
I heard the Renesas chip set is very robust and is known to work with my specific board.
Thanks for the help

No problem - hope your new card works!

So just to update, I got the card that I mentioned above (with Renesas chip) - it works (mostly). Windows detected it as soon as the card was inserted (before even using the drivers cd that came with the chip) and the two USB 3 ports on the card itself are now detecting my USB flash drive

The part that's not working is that my case (NZXT Switch 810) has 2 USB ports built into the front panel, so I have attached the connector to the new USB 3 card, but these are not working. I'm not overly concerned, but I'll raise a new thread to ask about this issue
