Mbox 2 Pro and M-Audio firewire device specific issues

You should NOT use the AC adapter for the Mbox 2 Pro unless the firewire port on your computer doesn't supply power - for instance, if it's a 'mini' firewire port with only 4 pins. Doing so can cause 6085 errors.

Mbox 2 Pro and most M-Audio firewire interfaces do not support FW800 connections anywhere in the chain. If you only have a firewire 800 port on your computer, you can try using a FW800 to FW400 adapter cable however keep in mind that this is not the ideal solution and may still be problematic. A better solution is to get a FW400 expresscard (for laptops) or PCI/PCIe FW400 card (for desktops) and connect your interface to that. The Siig 2 Port card (link to expresscard or PCIe versions) has been shown to be suitable for this situation.

If your computer has both FW400 and FW800 ports on it, they're most likely using the same bus and the above info would still apply, though you have the flexibility of connecting any firewire drives you're using either to the FW400 or FW800 ports on the computer or to the card, as long as your interface is not on the same bus - so if you connect your drives to the computer ports, connect your interface to the card or vice versa.

If your Mbox 2 Pro is not being recognized it may be due to corrupted firmware. Please follow the steps in the article below, as it should fix the problem:
