Thanks for the quick responses. I am running everything as root, I have
created the mount point directory, and I am using --foreground, but
owserver still exits immediately with no output.
Specifically, here's my /etc/owfs.conf (with comments removed to keep this
message shorter):
error_print = 2
error_level = 9
! server: server = localhost:4304
server: usb = all
mountpoint = /mnt/1wire
allow_other
http: port = 2121
ftp: port = 2120
server: port = localhost:4304
And here's my mount point directory:
root@raspberrypi:~/ow# ls -ld /mnt/1wire
drwxr-xr-x 2 root root 4096 Jun 9 22:53 /mnt/1wire
When I run owserver with the following command, it exits immediately with
no output.
root@raspberrypi:~/ow# owserver --foreground --error_print=2
--error_level=9 -c /etc/owfs.conf
root@raspberrypi:~/ow#
I've also checked the log files in /var/log (syslog, messages), and there
are no owserver-related messages in them.
In case it's relevant, here are the messages that show up in
/var/log/kern.log when I first plug the LinkUSB into one of the Pi's USB
ports, showing that system is recognizing the LinkUSB:

Interestingly, if I change the line "server: usb = all" in /etc/owfs.conf
to "server: FAKE = DS18S20,DS2405", the owserver command above does not
exit --- the process seems to run, but I still get no output on stdout,
stderr, or in the log files.
Also, when I run owserver with "--help", it does print the help message,
which shows that the owserver program is definitely installed and runable:
root@raspberrypi:~/ow# owserver --help

Syntax: owserver [options] device clientport
Help resources:

owserver --help=job Job control and debugging
owserver --help=temperature Temperature scale and device format options
man owserver man page for this program
and man pages for individual 1-wire devices e.g. 'man DS2409'

Do you have any additional suggestions about what could be wrong? I don't
understand why I am not seeing any error output at all.
Thanks again!
