The AW2 and AW8 Sound Manager drivers are for using the cards with software that doesn't "talk" directly to the card rather talk thru the OS.. LogicAudio and Waveburner talk directly to the card and therefore can't find it if it is assigned to Mac OS. Presently the Sound Manager driver and the direct driver for Waveburner/LogicAudio aren't multiclient (allowing several programs/OS to use the card at the same time). You can have Logic release the card when it's in the background so another program can use it. I don't remember if Wavewburner does as well.
