Reading the /bus.0/simultaneous/single_ds2400 node issues a READ ROM (0x0F) command. The result in both cases is the ID of the single chip connected to the selected bus (here: bus.0).
e.g. # owserver --i2c=ALL:ALL $ owread /bus.0/simultaneous/single Please note you cannot use these nodes with the DS9490 host adapter, as it already has an iButton built-in. Connecting another onewwire chip and issuing any of these commands results in wired-and garbage data.
