Well and tried that and got an interesting result. I had previously installed the demo of USBVision X to utilize the VideoBus in OS X. I had since deleted the program because it demanded $20 to remove its logo from the video screen and not quit after 10 minutes, but the files in the Library folder remained. When I plugged in the VideoBus, the computer recognized it as an audio input source though those USBVision drivers that were there. But there were no options as to what to do with the signal that it was definitely getting. I opened up GarageBand and tried adding a new live instrument but the only input option i was given was the internal Mic, even though in the Sound control panel I could choose between the two of them. Any ideas?
