    Korben,

    You can try the code I posted here.
    I modified some of Jon Williams' code from the April 2001 issue of Nuts & Volts.
    It should show you how the 1-wire search algorithm can be done. Mind you, the 1-wire
    network can not tell you what order the devices are on the cable, unless you're using
    the REALLY (this year) new devices from Maxim/DalSemi.
