Forget the DS2482 behind a DS28E17. With all the onewire protocol
overhead, the DS28E17 I²C has a net data rate of about 1000 Baud.
That's way too slow for a DS2482 on it to be useful to anyone.

Put some arbitrary I2C sensor to it. Or more that one. There is some
example code for the DS7505. Or you could try to hook up a kernel driver
to a DS28E17 I²C slave.
I'm most interested if you have problems following the documentation.

First give me a pointer where you have been stuck last time. I cannot
tell you that.

Matthias' territory, sorry here.
Kind regards
