Smoke billowing out from under the panel while taxiing for takeoff in friend's RV-9..... Returned to hangar to troubleshoot.
Found a very fried metal-cased USB flash drive in a Dynon data dongle that had bumped against a hot 12Volt buss terminal behind the panel. The longer than necessary USB cable wasn't secured properly. When the metal flash drive contacted the 12V buss, the entire dongle cable went up in smoke and fried all of the data & power wires inside the Skyview HDX 10" display's 37-pin DB shell. It also fried the USB Wifi adapter plugged into the unit's built in USB socket. Fortunately, the actual Skyview unit survived without damage.
Lesson learned: Secure your wire bundles and data cables behind the panel and never use a METAL-cased flash drive near a hot voltage source.
