Hey Clnilsen, thanks for putting together these instructions! Very much appreciated. I followed them, but for some reason the light in my Tardis isn't lighting up. I think I have a slightly newer version of the USB hub than you do (see picture). Before modifying the USB Tardis, I verified that the light worked. I have also verified that I am getting electrical current all the way to the LED wires. I checked polarity too. Not sure what else to do. Any ideas guys?
