Paul, Thanks for the tip. I tried it and, sure enough, see an 81-family DS1420. I'll try hacking together another cable and see how that works - hopefully the problems will be fixed.
2 quick quesitons: 1) Do I need to restart OWFS after adding a device, or can I just keep everything as is and plug in the temperature probe? 2) More important - am I correct in my findings that my DS18S20P (sampled from Maxim) does NOT require Vdd to be shorted to ground for parasite power? I've tried it both ways...
