Maya44 USB Recognition Problem with Mac

I recently upgraded to Mac OSX 5.5 (Leopard) and I've been having issue with the computer recognizing the Maya44 USB driver for my Vestax VCM-100. Within the "Audio Midi Setup" in mac, the controller shows up fine under "Midi Devices" but under "Audio Devices" there isn't an option for Maya44 USB within the drop-down boxes for anything (ie. Default Input, System Output, Properties For etc.) There is an option for "MAYA44 USB (Aggregated)" within the "Properties For" drop-down, but it doesn't seem to do anything meaningful, and obviously you need all settings available set to Maya44 USB.

Even more puzzling, is that I've gotten it to work a couple, seemingly random times. After uninstalling everything (including Traktor), and hooking it up, it has shown up properly (though only about 3 times), only to have it disappear again once I remove the device.

On an unrelated note (perhaps related?) I've noticed that now when I turn on my vcm-100, the LED lights blink a few times when they didn't before. I haven't found any info about what this could mean, though.

A bit of a tricky subject, and it may just be a glitch I have to deal with somehow, but any help/input would be much appreciated.
