Hello good night everyone. My problem is in a hitplus microcomponent change the usb port because it was damaged and shorted the computer and turned off. So I changed the usb port and now I want to change the computer to usb option and it doesn't change. The button works correctly. I tried with the cell phone and just put it in charging mode I put a pen drive and turn on but it does not change to the usb function. I hope you understand my problem thanks
