using Shure SM 58 and Steinberg CI2 USB studio to record

I would appreciate some help if possible. I am wanting to use my Shure SM 58 to record in Audacity 2.0.3. I have it connected to my Steinberg CI2 USB studio which is connected to my HP laptop (using Windows Vista Home Premium). When I try to record Audacity still uses my computer’s microphone to record. I must be missing something??

Connect the USB interface before you open Audacity, then select the USB option as the Recording Input in the Device Toolbar.

Thank you…thank you…thank you. Success!
