A hardware preparation is needed (only for R2!) if you want to use USB for powering the device during EFM flash process.
Shown picture is the Bridge R2 version where two not used copper traces need to be cut if you want to use the current power connector during updating and connect two wires between GPIO4 and C2Ck and GPIO5 and C2D. These changes can be permanent as they do not interfere with the normal Bridge functionality and it also allows for easy changing of firmware in the future.
