    Lenovo Y50-70 usb ports

    Hey guys,
    i got both of my usb 3.0 ports stop working when connected my phone. Now i get message that the usb is draining too much power and was disabled.

    I got the schematics but can't find any boardview for this mode.

    Can you help me where to start and what can be the most possible cause?
