Strange i2c-1wire problem

Hello, all.

When using the DS2482-100 chip on my Raspberry Pi, I can see 9 temperature sensors using OWFS - most of them DS18S20, but 3 are DS18B20.
When I disconnect the chip and connect it to Banana Pi right next to my Raspberry, the Banana only see the DS18S20s and not even all of them - one (on the longest data lane) is missing.
Seems like a power problem - the DS2482 is powered using the 3V3 from Banana and it seems the parasite power is insufficient.
Does anybody else have some experience with the DS2482 and powering it from the 3V3 line on Banana?
Can the voltage regulator there be less precise than the one on Raspberry?
T.S.  
I am using the same chip without any problems. More than 20 sensors white parasite powered are detected. But with short cables ATM.

Hello,

I have a banana pro with Lubuntu and i want to use 1wire with Temp.Sensors DS18B20. But it´s not working. What have i to do for running it. Which drivers or library´s are needed.
