If Logic’s I/O plug-in doesn’t see the H9000’s USB I/O then that leads me to believe that you’ve selected the Apollo as Logic’s audio interface instead of the H9000+Apollo aggregate device.

Here’re the USB sections of the manual:

And here’s a video on using the H9000 with an Apollo: https://www.youtube.com/watch?v=V0zxHeCo_5M

Let me know if that helps.
