Windows XP Digital Signed Problems

I just purchased a “Zircom 4 Port Multi-function USB HUB,” but am unable to use it because there is no driver compatible for Windows XP. The Zircom cd which accompanies the HUB has a WIN 2000 Driver, and the Zircom site, now Intel, recommends the WIN 2000 driver. There is no XP driver update, and Intel has no plans to issue one. However, when I download the WIN 2000 driver and try to install the HUB, I get the same message, “installing this device will cause your computer to, etc.” These frightening messages short of giving Bill Gates your first born are enough to make me go back to WIN 98 SE. At least it worked. Enough diatribe, anyone have a solution? I need the ports!
