I just re-read your email. Just to be clear I don't have a problem with the sensors being discovered, they certainly are being discovered. They are just not giving a temperature reading (that might be what you meant).

Ok, I've spent the last week chaing this down.

1. We conform to the DS2409 datasheet.
2. We use the same algorithm as digitemp (though digitemp only supports one level of branching).
3. We use the same byte sequence as digitemp.

So what gives?

I noticed a few things
1. I wasn't turning off branches properly -- I'll fix
2. digitemp doesn't really work either.

Yup. I have a 100 sensors network that is fully discovered in the root branch of either digitemp or owfs. Only a few sensors are seen in a main or aux branch.

Conclusion -- the 1-wire hubs are poorly suited for multiple sensors.

Next fix attempt -- I'll attempt multiple "discoveries" when working on a branch to perhaps get over the problem. Not efficient, but working is important.

I just tried powering the ds18s20 and it made no difference still reads 85. Don't know if that narrows down any variables.....
