I have also noticed that setting simultaneous does not work through a
hub. When I try it (I set the simultaneous/temperature file on each
channel) I don't get any errors and the readings are fast as they are
from the cached directories, but the readings for values that I know are
changing remain the same for many minutes then jump several degrees. It
could be something wrong with my setup but I haven't been able to find
anything.

Hi Don,
I spent some time testing. Although I can't get owserver to crash, I
do see that reading some entries in the /simultaneous directory clears
the cached directory listing. "dir /uncached" still works.
This is clearly an error and will be fixed in the next release.

Asking after much Googling and checking the owfs site. I'm trying
to understand why when I click on an owhttpd (started readonly)
"simultaneous" link it kills owserver.
I can see bus activity started on the adapter (LinkUSB blinks
actively) and then owhttpd listing no longer shows any devices and
a process listing shows that owserver goes missing. Restart of
owserver brings everything back fine and the 1-wire network seems
stable otherwise.
BTW, same thing appears to happen via owfs/file system:
cat /srv/http/1wire/simultaneous/temperature, which returns
cat: /srv/http/1wire/simultaneous/temperature: Input/output error
Owfs suite version 2.9p0 on a Seagate DockStar running up to date
Arch Linux ARM. LinkUSB adapter connecting a single short 1-wire
bus with 5 devices: 4 DS18xxx and 1 MS-TH, all parasitic. A second
machine with a 2 device bus behaves the same.
