From: Jan Kandziora <j...@gmx.de> Subject: Re: [Owfs-developers] Temperature sensitive bus timing using DS18B20 ... AS A SIDE NOTE, you have DISABLED the kernel's w1 drivers if you don't use them? If not, you'll get a conflict between the kernel driver and OWFS accessing the host adaptor at the same time, leading to exactly the scenario you've described (magically disappearing chips). Jan, Just checking... Since I've never been clear about the relationship of my default Ubuntu install of owfs to w1... Are you saying that even if we don't edit owfs.conf to explicitly enable w1: --- # ...and owserver uses the real hardware, by default fake devices # This part must be changed on real installation # server: FAKE = DS18S20,DS2405 # LA140622 commented # # USB device: DS9490 #server: usb = all server: w1 # LA140622 added --- It will still be active? Or is that "server: w1" setting the default when you build your own owfs, and it is only the Ubuntu version that doesn't include it? In my system nothing was happening on the bus until I added the w1 line. I'm also confused by your "kernel driver and OWFS accessing the host adaptor at the same time" line. Doesn't "host adaptor" imply USB or some other hardware beyond the simple hardware I/O line that w1 accesses? Maybe w1 could be considered the conceptual equivalent of USB or some other host adaptor, like it appears in my owfs.conf, but accessing a totally different hardware bus? Or have I missed some basic concept here?
