I suggested a "hack" to outline the source (IMHO) here
http://www.mail-archive.com/owfs-developers@lists.sourceforge.net/msg086
A few weeks ago, there was a discussion about the unstable owserver with usb
and longer cables. Is there a solution for it?
On my setup (see below) i have a similar problem where it falls of at
different intervals.
I recently experience a similar problem? :
i have a diy usb uplink with 4 Ds2423 c
I Think it should be easy for Michael to organize something like a
remote access to a testbed. He has a lot of devices :)

To hunt this down, you find that heavy USB activity causes communication
failures and puts owfs is an unusable state? I need to create a test bed to
mimic and correct this.

Err, referring to
http://article.gmane.org/gmane.comp.file-systems.owfs.devel/9120
Current owfs is really unusable with DS9490 and the older ones have some
issue with libusb under OpenWRT, I'm stuck a little here; tried many
things but when I touch code usually afterwards it's more broken than
fixe
Thank you for your investigation. Let me see if I can fix it this weekend.

well must check source code and see if it´s a time problem on

Just to further specify:

x86/Debian lenny (though: other cabling, not that long but worse; will
try to reproduce in testbed with capacitors tomorrow)

yes, here is the same problem but i couldn't test with rfc2722 since it's a
new feature, but with -d /dev/ttyUSB0 this problem occur in the same
situations that you showed

I have a similar problem, with owfs 2.7p32-2 and 2.7p38-1 on an nslu2
running unslung: when using temploggerd and a script, owfs crashes
The script now checks if everything is ok, and does a restart if not, but
the temploggerd graphs look all messed up.
Someone suggested to use a serial based de
Hi Paul, Roberto and all other 1-Wire freaks,
during some further tests I found out, that until version 2.8p2 the OWFS was
not afflicted by this problem, from my viewpoint this is OK and runs stable!
It looks like the problem was introduced with 2.8p3 and 2.8p4 versions, see
here:
- The 2.7p33 wo

sorry, I don't have an usb->serial adapter here and also no DS2480
It looks like restarting owhttpd is equivalent to restarting owserver

with ser2net and ds2480 i could reduce this problem, turning ser2net
down, wait a moment and restart ser2net
ser2net is a serial-tcp program i'm running it at ARM device (android
with linux 2.6.29)
and at server (x86-64) i'm running owhttpd with command option: -d

maybe another option should be added
--device-reconnect-time=0 (don't use recoonect timeout)
--device-reconnect-time=10 (reconnect after 10 seconds)

HIS PAUL READ THIS TOO, MAYBE A BETTER SOLUTION FOR BUS MASTER SPECIFIC
:D i found this too with ds2480b!
maybe a single workaround (ugly, but works) is a counter at device
for example after 10 reads, close and open device (/dev/ttyUSB0 or other device)
this works like cron restart, but it's faster
Hi all,
probably I've found a funny bug in the owserver in relation to USB
Bus-Master and longer cables. This was mentioned before in
http://old.nabble.com/Re%3A-How-to-enable-statistics--p33202282.html this
posting very fuzzy, but now I was able to reproduce it in my lab:
1. Install OWFS 2.8p1
