Sometimes Ubuntu will freeze for a few seconds when you plug something into a USB 3.0 port; when Ubuntu comes out of the freeze, the device is still NOT recognised. No problems with USB 2.0 ports and devices. The USB 3.0 on this computer only works in Windows 7 (I'm dual booting Ubuntu 13.10 and Windows 7, both are 64-bit).
