I just bought an M13 today (so excited). Got home plugged it in and it did exactly what you are describing (so disappointed). Turned it off and on again..... same, repeat.......same.plugged in my usb midi and tried to update with midi ox....... nothing. Turned off then on..... nothing. Plugged in my Audiobox USB to use it's midi. Had to download the drivers for the audiobox. While I was waiting I had the crazy idea to unplug the power and turn the M13 on to make sure anything internal that could be was electrically discharged. Replugged the power and turned it on, got a different sequence of lights on starting up but still no dice. Progress! After repeating the process a few times of unplug power and turn on (without power cable connected) then replugging power and turning on it is now 100% functional. I am currently updating to firmware 2.04.00 (it was originally saying v0.02b or sum such on the second screen while it wasn't working) but so far that seems to have woken this thing up and got it out of it's coma. It just finished the update and rebooted itself perfectly.
