I just installed Ubuntu on my HTPC - all very exciting.
I have a network cable plugged in right now but need to setup the wireless. Previously (when using Windows 7) I had used a Sweex wifi USB to connect to the net. Since installing Ubuntu, no wifi networks are available so Ubuntu clearly cannot see it.
If I run lsusb in the terminal I can one of the line says:
Bus 001 Device 003: ID 177f:0153 Sweex
