both usbs not working. try all functions. short keys, removing battery. every option possible u can find online. its not worth be buying you mainboard. there must be someone who knows how to fix the main board on here to help me out. now in system report it does not show USB 3/.0 Hi speed bus and super seed bus but shows trackpad bluetooth etc & camera. sometime when i plug something into one of the usb slows a warning comes up saying its drawing too much power. but still nothing works on them.
What are you plugging into them? Try something like an external keyboard that doesn’t require a lot of power. It may be the device not the ports.
