The reason of shorting USB / power supply: one of the MLCC capacitors was shorted. There were two 1206 capacitors in parallel, the other that was working had 47 uF capacitance. Not having 47 uF 1206 MLCC in stock I've replaced the broken one with slightly larger tantalum capacitor.

It looks like LiIon cell (042030, 180 mAh) also needs replacing.
