Though Maxim's list isn't complete as it doesn't has the third-party family codes in it. And the special DS2401 in the DS9490U host adaptors is also missing and so on.

Our own list is a bit imcomplete as it only lists the chip-packaged versions of that device, which are named DS2502. The can-packaged version is named DS1982. See page 2 of the datasheet. http://datasheets.maximintegrated.com/en/ds/DS2502.pdf http://datasheets.maximintegrated.com/en/ds/DS1982.pdf The DS1982U has family code 89. Other that that, it is functional identical to the 09 devices. See page 3. http://datasheets.maximintegrated.com/en/ds/DS1982U-DS1985U.pdf Same for the other uniqueware chips. > 3. Why is DS2407 omitted as an x12 device? > OWFS never supported the special functions of the DS2407 because it was obsolete and widely unavailable even at the time the owfs project started. Paul haven't got the chance to get a single test sample, IIRC. http://pdfserv.maximintegrated.com/en/ds/DS2407.pdf Leaving out these functions, the DS2407 is just the same as the DS2406. > 4.

And no, I don't have access to the owfs.org website.
