Hello,
to evaluate that, I used newly flashed SD-card with Raspbian Buster with desktop Release date:
2020-02-13 and installed OWFS step by step not having enabeled the 1-wire interface but the i2c- interface via raspi-config. At the end two folders bus.0 and bus.1 were fond in /mnt/1wire.

the occuring error seems to be due to not having enabeled the 1-wire interface.

I repeated the procedure with the SD-card newly flashed after having enabled both the 1-wire interface and i2c- interface via raspi-config and got a working system with two folders bus.0 and bus.1 in /mnt/1wire and all sensors in duplicate.
Hope that helps answering the question "Do you have the DS2482 or the W1 kernel module enabled?"
What to do?
Regards
