I am running openSUSE 13.2, 3.16.7-7-desktop, x86_64. One port of my four USB 3.0 ports refuses to connect any USB 3.0 device at USB 3.0 speeds. It will only go so far as to connect the device at 480Mb/s (USB 2.0 speeds). All four USB ports are physically equipped for USB 3.0 (they have the extra pins). The other three ports on this machine all connect devices at 5Gb/s with no issue.

Is there a way to permanently make it such that devices plugged into the offending port will always be connected at their highest supported speed? I have checked my sanity to rule out any false positives, having tried multiple cables and multiple USB storage devices. This single port is the odd one out, as all other USB 3.0 devices function just fine at 5Gb/s on the other three ports. I cannot attribute its behaviour to anything I have previously done. Any help would be appreciated. -- View this message in context: http://opensuse.14.x6.nabble.com/USB-3-0-port-keeps-connecting-USB-3-0-devic...
