I had a working setup with this lighting rig I created and now it isn't working. I know the rig is ok, because if I just give it explicit commands on the chip it's fine. There is something that no longer works (post re-format, I might add) on the serial line.
I was always confused about the 'serial a' object I created. Is it possible that my computer now thinks of my USB ports as a different serial port? How can I find the name of it?
