Hi,
They are the _only_ guys in Hungary I know of who sell onewire stuff:

No webshop, no pricing or stock availability info. You need to call :)
I used them and a Polish webshop I can't recall right now. Availability
of parts is a real pain in Hungary. Th

You said also that you have a router? If you just want few thermometers

I assume that the serial port of the embedded system only provides 5V on
its signal lines. If the DS9097 expects 12V and uses a voltage regulator
to provide 5V to the bus, it will most probably fail.
Can you measure voltage between 1wire and gnd pins on your adaptor?
It should not be much less

So you've already done a lot of debugging -- the fuse system works,
and the hardware works on another system.
Thus the problem is with serial port handling (hardware or kernel or
maybe timing).

There are two files under the owfs mountpoint named "shorts". One in the
./bus.0/interface/statistics/ and one in the
./uncached/bus.0/interface/statistics/
Both of them contains "0"
