From reading this board, I know that the Ethernet chipset can make a difference in performance. My question is whether the same is true for the USB controller. Are there certain USB controllers that are known to be more robust or higher quality than others? I have found that high priced USB hubs perform better than low cost USB knock off hubs. I am wondering if the same is true of the controllers found on motherboards. I am not really looking to optimize speed as much as connection stability.
