1-Wire-Sensors on LM5p2-KC

[Todayslife]

you can have 1-wire on this device as well, through USB-1wire adapter DS9490R. We have built-in driver for that.

Thank you Edgars for your valuable answer.

So, I understand; integration of 1-Wire-Devices on LM5 is possible by using its USB-Interface.
Thus, we will see, where we may find this "DS9490R#-ND Dongle" - which seems to be rather difficult to get - at least in Switzerland.

Please allow two follow-Up-Questions:

a) On LM5p2-KC; Would there be any other (field proven) methods available like for instance by using interfaces like; 
- RS-482
- CANx

b) In case, using USB-Interface on the would be the only (yet) available method, would you know any alternative arrangement / packaging / housing for the "DS9490R#-ND Dongle" ... eg. something, that would fit on a DIN-Rail and being equipped with terminals?

Kind regards
