I just plugged in my gear tonight for a flight and noticed my left MFD isn't working. After a few unplug/re-plug, it still doesn't work. The right one works just fine.

My MFDs are screwed onto my front console dash, and all my gear (TIR, TM Warthog, Saitek pedals, MFDs) go into a powered USB port so it's just one USB from the port itself to my PC.

Any way to try to fix this, or should I just go straight to TM support?
