Unless the modem has a built-in router, it normally allows only one IP, so connecting two computers wont work unless the modem is specifically made to allow 2 connections. To connect more than one computer, you can just get a wireless or wired ROUTER which is very cheap now. And a router offers a built-in security firewall. Without it, you better have a decent software firewall like zonealarm or other...

"If the cable modem has both USB and Ethernet connectors, only use one or the other, not both."

These links say that it's better to use the ethernet instead of the USB:
