I built myself a PC using the Asus P8H61-MX USB3 motherboard. It has 2x USB 3.0 ports on it. I plugged my USB sticks in and nothing happened. I plugged them into normal USB ports on the same motherboard and it worked. I checked in the BIOS and USB 3.0 is enabled.

I looked on the Microsoft website and MS say:

"Make sure to use a USB 3.0 port for USB 3.0 devices. Otherwise, you can use the most convenient port available."

So does this mean USB 3.0 ports don't let you use a USB stick that isn't USB 3.0? If they don't, that's fine! Just want to be sure.

Thanks in advance.

    you can use legacy usb devices in usb3 ports no problem. perhaps the driver isn't installed in windows? (windows 7 and lower won't recognize the usb3 ports until you install the corresponding drivers)

  • Thanks Nicolas, It was a driver issue in the end. I used the CD that came with the motherboard and found a driver called 'Asmedia USB 3.0 Driver'. Installed and works perfectly. Thanks!

Can you re-check. I see your motherboard did not have any USB 3.0 port include http://www.asus.com/Motherboards/P8H61MX/#specifications

I guess maybe your PC-case did have support USB 3.0 on it, but because your motherboard not. So these port might not (or forgot) connected to your motherboard which cause there port will not work.

For more information: USB 3.0 is compatible backward to USB 2.0 so if you plug-in any device, it should work.

update: Your motherboard have 2 USB3.0 port at at back panel, and do not have any to connect to font panel. So, it can be true that your USB3.0 port on your case is not connect to anywhere

    Thanks. I fixed this by installing the USB 3.0 driver from the CD that came with the motherboard. I didn't know USB 3.0 needed a driver to become backwards compatible with USB 2.0 Thanks.
