I have a Intel Grantly structure MB.

2 ports USB 3.0 onboard from PCH C612.
I have installed SUSE 11.3, I found the USB 3.0 Port only support USB2.0.

When I keyin #usb-devices to see the version of USB, It showed Ver=2.10 in SUSE 11.3

But, In the RHEL 6.5 which could be Ver 3.0.

Is that a limitation for SUSE 11.3 OS??

As SUSE offical web said, USB 3.0 support for Intel(R) 7 Series/C216 Chipset Family.
