My DS2483 sample arrived today so I had to make my Raspi boot the new kernel to support it. The problem was with the supporting boot files which needed to be updated, I got them from here: https://github.com/raspberrypi/firmware, I used the new 3.2.18-rpi+ kernel with i2c support form here: http://www.bootc.net/
It is working now, but I'm not sure whether the chip should be connected to the 3v3 or 5V supply, I think it is safe to connect it to 5V, but I have connected it to 3v3. I am not using an i2c level converter, do I need to if I power the chip from 5V? Anyway the 1wire parasitic device I have connected to it is visible but not reliably readable. to make it readable I had to issue the --ActivePullUp switch on the owserver command line. The 1wire bust will be getting only 3v3 which will explain the unreliable result, this is why I wonder if it is safe to put 5v onto the chip without a level converter.
