Hello again. I'll post here instead of creating a new thread since the problem I'm facing is a continuation of the one discussed above.
I finally got all my extra LEDwiz boards and extra RGBs. I hooked up all 4 with the red 5v line I had spliced into from my power supply. Each has a cable from the 5v slot (the one next to ground) and they connect together and then run to said power supply. I have all the buttons hooked up in the same manner as before, R, G, and B each going to its own port, and the black ground cables hooking together in a giant chain till again, returning it to the spliced (black) power supply cord. My daisy chain randomly includes the ground ports on the LEDwiz boards. I booted up the computer and things appeared okay at first but LEDblinky wouldn't illuminate anything, even with the simple LED test. I powered down to double check my connections which appeared okay and tried booting back up. The power button was illuminated but pressing it did nothing. I disconnected the 5v and ground wires and tried again, computer booted up no problem.
Oh, it might also be worth mentioning that all 4 LEDwiz boards plug into a single unpowered USB hub. This then connects to the computer.
Any help figuring out what I'm doing wrong now would be appriciated. After slaving over that CP for a few days I'm pretty eager to get things lit up.
