I use 4 channels on the hub at the moment, I have -
2 DS2406 + 2 temperature
2 DS2406 + 14 temperature
7 temperature
1 humidity DS2438
The temperatures are a mix of DS18S20 and DS18B20

Hi Mick,
Unfortunately, I have exactly the same problem here. Devices are
missing especially after some error occurs on a bus. Somebody believe
that it is owfs bug, but nobody knows how to fix it.
I tried to place some decoupling capacitors to reduce errors without
great luck. Now I just restart owserver every 3 hours and this makes
my system more stable.
Three is a thread here about construction USB - i2c - 1wire hub, but
the approach should be tested.
How many devices do you have on a bus?

Sorry, yes that is important info:)
Ubuntu 10.10 server
owfs version: 2.8p13
libow version: 2.8p13
DS9490R USB busmaster
Hobbyboards 6 channel hub
The problem sensors are all on the same channel, but is is not all of
the sensors on that channel.
I used to use a DS9097U and don't remember seeing the problem then.
That just packed up completely which is why I changed
Cheers
Mick
