To solve it, I replace F3 and F2 for some salvaged from a old PC main boards. Original RPi USB ports polyfuses, 140mA each. Power input polyfuse, 750mA. F3 polyfuse removed and PCB cleaned. Polyfuse F2 removed and PCB cleaned. Polyfuse F2 damaged when removed. New" 1600mA polyfuse installed on F3 position. Original F3 750mA installed on F2 place. IPAQ PSU 5V @ 2A.
