no usb works. USB 2.0 not working. USB 3.0 not working. It says device not recognized

Hello, I have lenovo v310 and no usb is working. When USB is plugged in, it says the device is not working. When I checked, I saw that all lines went directly to the CPU. In this case, is the CPU problematic? Or am I looking in the wrong place?

Did you find another bios?

I hope you find a solution :(
