Hey, I'm trying to get my wii u sensor bar to work. I've plugged it into the red plug at the back whilst the wii u was system updating. Booted up dolphin on my PC but the lights don't seem to be working. I've also checked by looking at it through my phones camera, no lights visible. is it defective or do you need a game in the wii u for it to power the sensor bar? I just checked on my friends wii u upstairs and its the same deal. I powered on his wii u, shoved the camera by the sensor bar and it doesnt register it.
