Let me put it this way If everything is functioning than don't use the patch... If you often have problems with your USB not functioning properly than you might want to use it.... BUT I think microsoft has a patch out for USB functionality out so you might want to try that first. I would advoid putting the VIA drivers on except for a LAST RESORT. If you are running windows millenium dry deleting the USB drivers in Device Manager and let them reinstall themselves. Hope this helps.
