Wireless Adapter question

Hey guys! I've recently got myself a new computer. Well, new will be a lie, since this thing has long since reached that age when a child goes to school. Since it's old, I've decided to try Linux on it, knowing it won't be able to run windows XP.
Anyway, so far for my internet connection I've used Edimax Wireless Adapter. It's a usb thing, looks like a flash drive, that allows you WiFi connection. Well, two problems:
I no longer have the installation CD it came with, and it needs a software to run with.
And even if I did know where the CD is, I doubt if it would run on Linux...
I'm using Ubuntu 11.04. Any suggestions?
