I have had 2 laptop USB ports die slowly (all ports slowly got flakier, until the caused slowness issues from seemingly random interrupts). I suspected it to be heat and poor cooling design around the usb chips. So far 2 previous models slowly (not from the same labeled provider) became less and less stable with disconnects more and more often.
