Hi All, Your going to love this.
I have just found out by looking at the PCB inside the Devo-M, and found out that it's Arduino Chip! The same as my APM 2.5 and the new APM 2.8 FC's.
So you can install the firmware from the Mission Planner software.
Just set your comport from 115,200 to 57,600.
Here's a link to a youtube video by diydrone
