First, like always some background info

My brother is building a new computer. But he only comes to my house when he gets vacation in college (he lives on-campus). I have a Cable modem, the cable modem has a Ethernet & USB connector, as far as I am concerned you cannot use both at the same time (never tried it). One time, while trying to set up a friends XBOX and computer to work together I came across this bridging theory, but never really tried it.

So now, I'm going to bridge my computer and my brothers computer but without buying a new ethernet card (no more PCI slots on my pc, and I don't want to remove one of my PCI cards for > 1 wk). When I came across the XBOX theory a while back, I noticed that you can connect the modem to the NIC card, and then connect a USB cable to your USB slot and the opposite end of the USB cable to the XBOX then configure some settings.

Now to the point of this post, I'm using WinXP pro SP2, I don't seem to find that article again and google points me only to ethernet 2 ethernet bridging.
