Linux Users:
Linux Driver Instructions here: https://www.zamaudio.com/?p=953
Mac/Window Demo Driver - if it works you can purchase license.
Driver Download Info: http://www.usb-audio.com/download/
Usage:
1. Connected to a computer with (old) supported OS and Pro Tools installed:
Everything works already, so this mod is not for you. (Also, where did you get that time machine?)
Connected to a computer without drivers / Pro Tools:
2. Analog inputs are pre-amplified and sent to analog line outputs. (Mic/Line/Instrument switching works. Phantom power works.) No S/PDIF. No digital audio connection to host computer.
3. Connected to a USB power supply (not a computer):
Audio circuits disabled. Doesn’t work at all. No amount of trickery with resistors on the data lines will help. (This is actually proper USB device behavior: The Mbox must wait for a computer to approve its request for full power before it can enable the audio portions of the circuitry. It needs to be connected to a real computer to get permission, so it limps along forever when plugged into a USB charger.)
