2. I've read that a bug in the Maxim i2c implementation makes sharing the
i2c line fail in certain circumstances (search their archives).

that timeout would be more efficient.

I'm no i2c expert, but can you try /dev/i2c-1 /dev/i2c-2 ... ?
owfs merely performs: open(/dev/i2c-0,O_RDWR) so the real answer is
whatever device name is linked to the correct major/minor device.
Perhaps dmesg or /proc can offer more information.

Ok, I looked through the documentation.
You have multiple I2C slaves on a single bus. We currently cycle through the
available addresses and take the first responding one, ignoring the rest.
It looks quite doable to add support for more i2c adapters, but there are
some architectural issues.

DS2482 on that i2c master
--i2c=all # Every i2c master and DS2482 slave

If you want to go all out:
--i2c=/dev/i2c-0:2
for the device on i2c bus zero with address 2
, and ipaddress:3000
elsewhere.
Please report your success or problems.

My hard disk crashed solid. Ouch. So I set up Ubuntu 8.04 (64-bit)
Here's the steps for OWFS.
Basic ubuntu install and added lots of fluff.
Then for OWFS ---
sudo apt-get install cvs
sudo apt-get install autoconf
sudo apt-get install automake
sudo apt-get install libtool
# For filesystem
(but ugly): http://owfs.org/index.php?page=owphp
There is an example program in the code with some comments.
The syntax is the same as the rest of owfs -- the same device names and
property names.

Do you want to try this patch and see if it helps? Essentially we are
filtering for 85C and retrying unpowered.

Can you run with full logging (error_level=9) and see if it takes 2 or 3
attempts every time? I wonder if it's the attempts, or the code for powered
reads that is the problem.

I've not looked to well at the docs, but in a system with multiple master,
a hub, or even an DS2482-800 is it possible to see which adaptor / port a
