Unable to connect Alesis io2 Express to LE 5

I cannot connect an Alesis io2 Express to Cubase LE 5… I have the program installed and I am using Audacity to record, i have no clue what to do to hook up the pre amp Cubase LE 5. SOMEONE PLEASE HELP ME STEP BY STEP!

Download the ASIO4ALL driver and install, then follow the quickstart guide here> http://www.alesis.com/io2express and here> http://www.steinberg.net/en/support/downloads/downloads_cle5.html (getting started)

That Alesis should have its own ASIO driver no?

Not acording to the Alesis website.
