Mbox 3 Flashing light sequence.

I have been using my OS X Yosemite and Mbox3 together perfectly for the past 4 months, however my Mbox3 is now randomly flashing lights(Like it does when it boots) and my iMac says "Hardware not connected". I have updated all Drivers, checked the power source, changed the USB cable, and tried the Mbox on my other Mac that I have used it with before. Nothing I have tried has worked. Has anyone else had this problem/have a solution?


iMac: OS X Yosemite 10.10.5

Hardware: Mbox3

Software: Protools 12.2.1


Thank you!
