Hello,
have you build owfs self INCLUDING the USB settings?
Maybe when that be missing, you will never can read sensors.
Also will you will be sure, that OW_HTTPD will not access
to the USB-adapter during the time you start owserver/owfs?
The access from two program (server and httpd) at the same
hardware bring you up to problems.
Best regards,
Roland

No, no, no.
You have to decide whether you want to use the setup from the config
file or a setup on the command line. If you use both, the result is a
mess. First take care that neither owfs nor owserver nor any other owfs
related process is running, then do
$ sudo owserver -c owfs.conf
$ sudo owfs -c owfs.conf
Ok did that!

looks like it should be running but its not there!
oh and owhttpd is working as I can point my browser to it and I get output!
Thanks David
(or /etc/owfs.conf or whereever your config file resides)
Why? Because your config file says: "owfs, use owserver! owserver, use
USB!" That's a sensible setting because owserver is taking care multiple
daemons may access the onewire concurrently.
it just returns a prompt no output.
That's okay because it daemonizes itself when you don't specify
--foreground or --debug.
$ ls /mnt/1wire
bus.0 bus.1 settings statistics structure system uncached
but no devices?
Look at /mnt/1wire/uncached. Listing that one triggers a device search
on all buses.
owget /unchached returns
owget: command not found
Owget usually is installed at /opt/owfs/bin/. If you are using a
distribution package, you have to check whether it was built at all.
It's a useful tool for debugging, as it only needs owserver, not owfs,
not FUSE, no permissions, nothing.
owserver doesnt show when I look at top!
That's especially bad as you configured all the other daemons to use it.
Kind regards
Jan
