I found the problem. This is a 2 port adapter, I unscrewed one of the ports leaving only one attached to the plate, and there's no more sparks. I screwed the other port in, and it started sparking again, so obviously somewhere in the wiring of that port is bad.

The metal plate on the usb adapter is where I see the sparks. Once it makes contact with the back of the case where I screw it to hold it in place. The computer works fine, maybe I just got a bad adapter.

I just bought one of those usb adapter that connects to the usb header on the motherboard. When I power the computer on, I notice little sparks coming off the metal plate. Is there a way to fix this?
