Summary: I got the computer on 24 December 2013. The USB ports were not functioning properly. On one of the USB 3 ports it ran extremely slow and took several minutes to even recognize my 1 gig passport USB device. While another USB port was much faster. So I called tech support and showed them the issue (they took control of the computer for this) They sent a new cable assembly and a new motherboard. A tech cam on 27 Dec 13 and replaced my motherboard and assembly.
