Hi again,
after the measurement....
We tried a linux program to search the 1-wire bus.... -> so we installed digitemp at the same linux pc.
Sensors and values are found, but with owserver,we still didn´t found the sensors.

Hi,
ok, the PC was not connected, the multimeter was at Gnd and 1-wire-Data
The multimeter shows 4,93V all the time.
The buscoupler has a DS2480R+, hope it is also supported by the owfs :-)
info from the shop page:

The DS2480B (the chip inside a DS9097U) controls the strong pullup
automatically. If I read the sources correctly, owfs sets up the strong
pullup duration to "infinite" in the DS2480B configuration sequence, so
it should be activated.
But maybe it isn't?

Don't connect your setup to a PC. Power your host adaptor, put a
multimeter to the bus, and check whether it is still at +5V after a
minute or so. If not, connect a 1,5k resistor from the onewire bus line
to +5V.
