  // Method 1:
  // Search for devices on the bus and assign based on an index. Ideally,
  // you would do this to initially discover addresses on the bus and then 
  // use those addresses and manually assign them (see above) once you know 
  // the devices on your bus (and assuming they don't change).

  // returned. A zero might mean that the bus is shorted, there are no devices, 
  // or you have already retrieved all of them. It might be a good idea to 
  // check the CRC to make sure you didn't get garbage. The order is 
  // deterministic. You will always get the same devices in the same order
