My USB ports are not detecting my peripherals. The lights on the devices won't even come on. It started when I had my audio interface (external sound card) plugged in. I then plugged in my midi controller which never came on. Plus the interface just dropped out. It shut off and the lights went out. I restarted the pc then tried again. First the interface, lights came on. Then the midi controller. No lights, plus the interface shut down. Now, I can't get either to come on at all. I checked the peripherals on another pc and they work fine.
