    Hi all.

    I'm certain that I have all drivers installed on my R3, including the Renesas Electronics USB 3.0 (Host Controller and Root Hub).

    But when I plug in my USB3 devices, it tells me that "this device can perform faster." It does this only the first time I plug it in.

    What's a sure way of checking to see if the ports are working correctly? I feel like the ports on the left (two SuperSpeed ports) are running faster (depending on the device) even though it's giving me that error message.

    Thanks for any insight.

    if you have an usb drive 3.0 you can bench it with crystaldiskbench first on 2.0 usb port , then on 3.0 and compare the speed .
