I've got a project that I'm working on with the OctoWS2811 library.
This is what I have so far:

8x WS2812B strips of 120px.
2x 26a power supplies
Teensy 3.0 with OctoWS2811 @ 96mhz
I'm noticing that when I plug a laptop into the teensy that I get extra flicker on my strips. It doesn't matter much if the laptop is plugged into its own power source.
I've cut the trace on my teensy as specified here http://www.pjrc.com/teensy/td_libs_OctoWS2811.html so that the Teensy is only powered by VIN. The teensy is powered by one of the power supplies. The power supplies have their V- (grounds) joined. Also the power supplies have the same power input (L/N/E) daisy chained.
I am assuming that USB Is sufficiently grounded on the Teensy. Is this true? Do have I have to do anything else to join the USB and Teensy Grounds?
