I am installing Ubuntu 10.04.3 on IBM System x3400 M3 which is listed as certified for Ubuntu 10.04.
I was unable to configure Broadcom netxtreme II Gigabit Ethernet Driver bnx2 during that point. While troubleshooting for that, I noticed that the IP address I given during install got tied to usb0. Since I am first time coming across usb0 as an ethernet device, I thought of asking here. If I can assign an IP address to a USB port, how I can use it to communicate across network? Or is there any other use of having usb ethernet?
