When I plug in a USB Dual Pre via USB to my intel MacBookPro, it apears as "USB audio codec demo". This "demo" puts a beep into the recording every 20 sec's or so, and also allows for only minimal manipulation in midi set-up. Forums online point towards removing the USB "driver" in /library/extensions or in /library/audio, however, I do not find any files that match this in these ares. I have also combed through the system files, and have found nothing.
The manufacturer does not distribute software for a Mac "driver" as it is not needed. I think at one point I may have updated the ASIO, causing the issue, but even searching my drive for files installed by date does not show anything.
I thought i would ask the guru's here for input and experience. The Dual Pre is not a primary input, and is merely being used for flexibility within an aggregate device, but the "demo" tag prevents it from being included in aggregate device set-up.
Next step is OS reinstall...
Thanks in advance
