ws read problems using 1-wire hub

[tfrohling]

I'm having a strange problem when I use the hobby boards 1-wire hub and
talking to a 1-wire weather station. If I connect up the WS directly to the
USB adapter and use owwnogui, I get very few errors from the station and
things work just fine. But when I hook up the WS through the hub and
have it relearn all the devices and start owwnogui, I am getting...

Sometimes it does read it ok, but it's not at all reliable. I'm using owwnogui version
from the OWW 0.82.1-1 package on an Nslug running unslung.

Anyone got any ideas?

thanks,

Oh, here is my devices file:

Wondering if any of the various 1-wire parameters should be changed when
working through a hub.
