Recently my Mbox (3rd Gen) stopped working on my Windows 10 PC. Instead of functioning for audio output, the Mbox would crash Windows 10 with a BSOD.
The failure seemed to begin when I moved my PC to a new room, which involved unplugging and replugging my cabling.
After doing all manner of deinstalling and reinstalling drivers, I finally came across a clue on the page
http://avid.force.com/pkb/articles/e...d/Mbox-Drivers where it says, "USB 3.0 Ports not supported with Windows 7." I guessed that maybe this statement was not up-to-date and that the same USB3 incompatibility also exists in Windows 10. BINGO! This was the answer.
I moved my Mbox USB cable from my USB 3 port to a USB 2 port and VOILA, it started working again. Pity for those with newer PCs that have only USB 3 ports.
I found this solution perplexing, because the USB 3 spec is supposed to be backwards compatible with USB 2. So the Mbox should work on either type of port. It's disappointing that whatever is causing this USB 3 incompatibility has not yet been solved with an updated driver. Until then, just use a USB 2 port, and you're golden!
This problem was so troublesome, yet so simple to solve, I just had to share.
