In 2010, worldwide sales of Plavix topped $6 billion (yes...billion!). For a typical stent patient, one 75mg tablet of brand-name Plavix a day cost more than $210 a month. Those with drug-eluting stents (80% or more of patients) generally must take Plavix for a year minimum.

Re: USB port colors, nonfunctional port on X220. from some googling I think the Blue is USB 3.0, the Yellow is USB 2.0 always on, and black is normal USB 2.0. try lsusb and see if a USB 3.0 hub is listed. I am guessing at this because I have yet to work with USB 3 but I think it should be listed the same as USB 2.0.
