TASCAM US1800 not working with Mountain Lion

[ShredX]

I upgraded to Mac OSX 10.8 Mountain Lion in the morning. When I got home and plugged into my TASCAM US1800 audio interface, the USB connection light was on and I assumed it worked, but when I went into sound properties on my MBP, it wasn't visible. Tested by playing some music. It didn't play through the TASCAM US1800. Reinstalled the drivers and rebooted numerous times and Mountain Lion doesn't see the previously working TASCAM US1800. In System properties, it shows the TASCAM US1800 connected via USB. With the drivers uninstalled, the TASCAM US1800 still shows info in systems properties. Contacted TASCAM to inquire on compatibility with Mountain Lion and a driver update. Expected my audio interface to just work like it always has with Lion. Ideas? Can I downgrade back to Lion if necessary?
