i believe that's a software problem too
maybe review timeouts including usb pooling timeout (1ms for ftdi
ft232 usb-serial converter or any other usb converter)

hi ,
sorry for the late reply, but I'm still waiting for the temperature increases
in the local, because the installation is in the cold

The DS2450 sensor from that company has 5V and gnd outputs. Can you try
with a voltmeter to measure the voltage both alone, and when the DS18S20
sensors are connected?

Are you using 3 wires out of 8 in UTP?
I had a problem with 3 wires and when I added second wire for ground it
got better. But this was on much wo

What kind of wire are you using? 8 wire twisted pair(UTP) or maybe a
telephone wire.
If you have some spare wires in the cable try to add another G

Tell us about the wiring scheme. The USB9097 is PCSensors' system with it's
rather unique wiring method. I wonder if the power or ground is
interfering.
The full answer is that properly wired, all 1-wire slaves should be
compatible on the same bus.

hi,
with USB9097 then plug 8 DS1820 and 2 DS2450 i see only 8 x DS1820 ,
if plug only 2 x DS2450 , i see tow DS2450.
if plug only 8 x DS1820 , i see 8 X DS1820
why the DS2450 lost with DS1820 plugged ?
thank you--
