Default Pro Tools ran out of CPU power - Error Code AAE-9173

Hi All,
I've been having this error for months and it was driving me crazy as my CPU was NOT running out of power. I was convinced it was a bug with ProTools.

It turns out it was because I had my interface plugged into a USB3 port instead of USB2. Would not have thought that this would be a problem as they are supposed to be backward compatible.

I hope that this helps anyone else who has had a similar issue.
