While it's going to sound completely stoopid, one theme I've noticed is that it's recommended by several knowledgeable people that you disable Legacy USB Support on i865/i875. Nothing to lose by trying it, right? 🙂 Also (super long shot here), do you have any of your case's front-USB wiring plugged into the motherboard?
Also, if you have the Intel Application Accelerator installed, you might try uninstalling it.
