I assume we're talking about the DS2482-800 -- the 8 channel i2c-based bus
master.
The fact that a reboot doesn't fix the problem takes in issue out of owfs
(which should be entirely reset by a reboot) and to the hadware (which
might need a power cycle to fully reset).
The datasheet talks about

I see on the spec sheets for most devices it says max voltage is 5.5v,
from your experience is it possible to go above that and if so what is
the maximum?
The datasheet of DS2482-800 also says +6V is absolute maximum rating to
prevent permanent
Volt drop on some of the cable runs. Just thought if I started with a
higher voltage there would be more left at the end:) I need to work
through it all, probably double up on the +5v line as well to reduce the
volt drop but that means some fiddly soldering on the circuit boards
unless I can
Hi Paul,
Thanks for the suggestions. Yes the Sheepwalk adapter is based on the
DS2482-800. I can't see anything obvious in the logs, but I have done
some more investigation and now suspect it may well be a voltage
problem, so I am looking at ways to try to stabilise it.
I see on the spec

Before voltage drop on the 1W line gets a problem, you have a problem on
the GND line.
That is because when you have 1V drop

I strongly recommend to use a thick-gauge GND wire instead of playing
with the supply voltage.
Or use three wires for GND. (You do have a spare pair of wires in your bus
cable, don't you?)
Frankly, if I had thought of this, the first thing I'd try to fix
I have had a problem probably 3 or 4 times over the last few months
where I loose some channels on my 1-wire, this time channels 1, 4 and 5,
which I think is the same channels as before but can't be sure. If I
reboot it doesn't help, just comes up with the same missing channels,
but power
