This is because the driver input and output info is installed when using the factory drivers, but ultimately this is not a problem since the tracks are still numbered, just something I wanted everyone to be aware of. The only caveat is that with the generic USB driver loaded, your device Input/Output names will also be generic in your apps.
#M audio mobilepre usb driver not on the list install#
Under "Sound, video and game controllers" your audio device should now show up as "USB Audio Device".
