Tested mainline kernel 3.16.0-031600rc4-generic and the same behaviour exists, USB will work sometimes, this previous boot it was working. Is there a way I can provide information to this bug when the USB is working to provide further insight?
** Description changed: USB devices only work sometimes in Ubuntu. Seems since I started using this Z87 mb USB devices have not reliably worked all of the time. Expected behaviour is for USB keyboard, mouse and other devices such as microphones and portable drives to be detected.
