Yesterday I was booting my Raspberry Pi 4B into RetroPi. When I got onto the controller screen, I plugged in a Google stadia controller via USB. After I did that the whole thing shut off. Everytime I tried booting after the green reading light would flash only once for a split second. I tried cleaning the port, Recovering the SPI EEPROM (thought it was corrupted) and using different power cords. I am out of ideas and I really need some help here.
