Digi 002 not recognized as interface: Do I need to install Pro Tools 8?

I recently upgraded to a Mac Pro and have just installed Logic 8.0.2. I wanted to use a Digi 002 rack as my interface, but Logic does not offer it as a choice when I go to audio preferences > devices > core audio. I get 9 choices of devices, but they are all built-in. At first I thought I could install a Digidesign core audio driver and make the 002 show up. But I did not find any such driver available for download on the Digidesign site. Digidesign does say the new Mac Pros and OS 10.5.6 have been certified as compatible with Pro Tools 8 and the 002 rack.

Does this mean I need to buy Pro Tools 8, install it, and that's where I will get the driver that makes the 002 show up in Logic? Or another way of putting it, are you not able to use Digi hardware as your Logic interface unless you also have Pro Tools installed on your Mac?

Any advice much appreciated,
Jim
