2.8p14 / DS9490 disappearing

Hmm and while doing some more testing another one:
(I make a new post as I don't know wether it's related..)

2.8p14, pretty simple setup with 3x DS9490:
- - 81.40922F000000 one iButton on (directly with a reader-cable)
- - 81.35B62F000000 just some sensors on my desk, 1m cabling
- - and nothing on the third (waiting for an iButton to get attached)
- - The DS9490 are on a well-powered, proven USB hub

One DS9490 gets lost pretty quick, I did some debugging-output, attached.
- - I tried to stop it as soon as one went off fully and I did some runs
to get the smallest one, it doesn't always happen that quick but
reproducable..
In the attached log one DS9490 gets lost approx 190secs before it stops.

- -> owserver needs to be killed with -9 then and restarted to recover.


best regards

Michael

Hi Michael,
maybe what you experienced is the same what I already described in another tread.

- Is only one DS9490 got lost and the others still continue working?
- Maybe this one have a high capacity between data-wire and ground
  (due to a wrong placed Capacity or very long cable)
- Did you tried version 2.8p2 as workaround? In my case it solved the problem.

See my thread here

It surely is, my last summary posted here:
http://article.gmane.org/gmane.comp.file-systems.owfs.devel/9120

2.8p2 seems much more stable as the reset_errors are less frequent but
IMHO the problem stays the same..

I have 2.8p2 now running since weeks, in one special environment "tuned" close to the edge of non-functionality (with extra long cables and capacity), but it still works flawless, not one hanging owserver in several systems :-)
OK, you already had a closer look to the sources, maybe it is self-healing, but I don't care - it works!

Of course at the end I would appreciate having an up-to-date version working too...

Thanks a lot so far for digging inside
