For noisy lines this was a 'timeout' after which system considered attached
device as failed, the noisier line is the longer is timeout

I experimented with meters-long w1 wires and it required several
search fails to correctly determine that device disappeared

Guys, you so much overcomplicate things - this field is basically a set of in-memory flags
for attached device, there is no need to even think about how it is present in different endianess

Or do I miss something fundamental there? I wrote it gazillions years ago and probably already forgot something
