I put one of these in the Quicksilver: http://www.amazon.com/ADS-Technologies-Turbo-Upgraderade-USBX-2000/dp/B00006B6Q1/ref=cm_cr-mr-title Works like a charm. I installed some lonely piece of software that may or may not be relevant, just to be thorough. Unless there is some lonely well hidden software bit on a CD that came with your cards, just go ahead and switch to the ADS. Works good even through a D-Link hub.
