Ah, ok. So you have the w1 patch included.

Please, don't use the FUSE interface for anything but demonstration
purposes. It has some serious limitations which can't be avoided.
Instead, stop all ow daemons currently running (not just owfs, but
*ALL*), then do
# owserver --debug --w1
and, in another terminal:
$ owget /uncached/1B.F4DB40000000/pages/page.0 | hexdump -C
Please send me the log from owserver.

This is fine as long as you use only *one single* daemon, as all the
daemons including that configuration file are advised to access the w1
kernel interface directly. I recommend to replace it by:
server: w1
!server: server = localhost:4304
mountpoint = /home/pi/ow
allow_other
foreground
error_level = 2
That way only owserver accesses the w1 kernel interface, and all the
other daemons do it through owserver. Of course you have to run
owserver then.
As the configuration file isn't included by default but only when you
specify it on the command line, it's okay to leave it untouched and just
stop all the daemons started by default for debugging.
Kind regards
