There is a problem with the xhci_hcd module, any device connected to the USB3 port kills the controller with following output from dmesg: [ 109.374047] ALSA sound/usb/endpoint.c:498 timeout: still 3 active urbs on EP #1 [ 110.373720] ALSA sound/usb/endpoint.c:498 timeout: still 3 active urbs on EP #1 [ 111.373414] ALSA sound/usb/endpoint.c:498 timeout: still 3 active urbs on EP #1 [ 113.385736] xhci_hcd 0000:03:00.0: xHCI host not responding to stop endpoint command.

Apparently everything works fine on Windows and the USB3 ports can be used without problems.
Sorry for typo, the only one port working is the USB2 not the USB3
*********** MASS BUG UPDATE ************** We apologize for the inconvenience. There is a large number of bugs to go through and several of them have gone stale. Due to this, we are doing a mass bug update across all of the Fedora 19 kernel bugs. Fedora 19 has now been rebased to 3.12.6-200.fc19. Please test this kernel update (or newer) and let us know if you issue has been resolved or if it is still present with the newer kernel. If you have moved on to Fedora 20, and are still experiencing this issue, please change the version to Fedora 20. If you experience different issues, please open a new bug report for those.
After the Kernel update to 3.12.6 this appears to be fixed.
