I’ve done a bit of work on trying to get Mbox 2 working. My card didn’t “just work” so I had to do a lot of searching and I didn’t find the exact recipe anywhere, so to help the next guy, here’s my rundown on how to get it working.
Ubuntu 18.04 and Debian
Mbox 2 registered correctly, but when I checked with dmesg in the terminal, I would get a timeout error message and the device would get ignored.
There was no light in the card and nothing worked.
My firmware was version 1.24 and that was apparently too old, I had to upgrade it.
The version that I upgraded to was version 1.43 from http://secure.digidesign.com/services/avid/kb/downloads.cfm?digiArticleId=24364
I first installed the latest driver (XP in VM) and then I used a firmware flash tool on windows XP SP3 in a virtual machine to flash the firmware.
downloaded from here: http://secure.digidesign.com/services/avid/kb/downloads.cfm?digiArticleId=24364
It took several tries and reboots before it finally flashed correctly, but it worked in the end.
Getting a working XP system was the hardest part of the process.
At one point, I got a missing MCF71.dll error and I had to use a different XP VM image. DOn’t know if it’s related.
I tried to use the Mac_INTEL version on a 2011 macbook air, but it didn’t work since the program was apparently for power PC architecture, even though it should be for Intel platform.
