I have a detailed (errorlevel=9) log for owfs 2.7p24 (compressed this time). It looks very different than the previous log for owfs p2.7p22. Hope it helps solve this issue.

Are you running as root? (There are permissions issues with both
accessing the USB adapter, and unloading the ds9490 kernel module).

Also, what is the version of libusb?

Any hints in the logs (dmesg or /var/log/messages) about the issue?

That sounds like my problem, can't access the usb adapter.

These tests were on OpenSUSE.

Ubuntu 9 in a virtual machine also compiles and runs without
sigfaults. (except I can't access the USB adapter).

I will set up a real machine to test it.

Same problem using source from sourceforge.  I'm using Ubuntu 8.10, what
about you?

/opt/owfs/bin/owhttpd -V
/opt/owfs/bin/owhttpd version:
   2.7p24
libow version:
   2.7p24

I used cvs, I will try sourceforge.

I'm perplexed.

Obviously the code worked for me on my development machine. So I tried
a more realistic test:

I downloaded the file from Sourceforge (owfs-2.7p24.tar.gz)
Installed in in another machine in a fresh directory.
./configure && make && sudo make install
sudo /opt/owfs/bin/owhttpd -u -p 4444
It works fine with the blue adapter (DS9490R) and the AAG hub
(TAI-8595) and chips like the Hobbyboards 1-wire counter.

So now the trick is to figure out the differences.

The fact that an earlier recent version (2.7p21) works suggests that
kernel/hardware/module/udev/permissions isn't an issue.

Can you check the version of your newer code (/opt/owfs/bin/owhttpd -V)

Today when I downloaded from cvs owfs2.7p24 and compiled it everything
checked out until I tried to use it with my blue usb adapter (DS9490R).
Php, perl and owhttpd couldn't see the 1 wire bus, I kept getting not
found errors.  Daemon log kept showing "bad adapter" messages.  When I
reverted to owfs2.7p22 everthing was good again.  Any suggestions?  PS
owhttpd is listing devices again so some good came of this.
