.SH "DESCRIPTION"
.PP
The 1-wire search is a simple binary tree search.
For each bit of the address, we read two bits and write one bit.
The bit written will put to sleep all devies that don't match that bit.
When the two reads differ, the direction choice is obvious.
When both bits are 0, we must choose a path to take.
When we can scan all 64 bits without having to choose a path, we are done.
