HELP!
After a solid week of mining, my Neptune controller won't recognize my cubes. I have to be missing something simple because I now have 2 controllers like that. I've used recovery SD to RC6, updated to 1.00, 1.02, 1.05, 1.06s and none will see the cubes.
Instead of white flash that's about a second, I now get a short white flash 3x spaced out over probably 15 seconds. No green led

I'm sure this must be common, so what am I missing?
PS: All ribbons are firmly attached. Red strip towards corner of cube and groove in controller. I've tried just one cube and still nothing.
