Hi Paul
I think the problem is in owhttpd as owdir works as expected.
Version
owfs-2.8p16
Startup
/opt/owfs/bin/owserver -p 3001 --i2c=/dev/i2c-0:ALL
/opt/owfs/bin/owhttpd -s 3001 -p 3002
OWDIR
root@raspberrypi:/# /opt/owfs/bin/owdir -s 3001
/28.E1C96F030000
/28.26F06F030000
/FC.000000000015
/bus.1
/bus.0

Then if I select Bus.0 from the list it now shows Bus.0 and Bus1

Subject: Re: [Owfs-developers] Can someone explain the bus listing owhttpd
That's interesting.
I think this is an (unintended) consequence of some internal changes.
The initial design of owfs was a single bus adapter. That was expanded to
multiple adapters with the master-specific information (port, speed, etc)
stored for each adapter.
When newer "multichannel" adapters came out, it got more confusing -- like
the DS2482-800 and the HA5 (and soon the EDS OWSERVER-2) which have multiple
1-wire buses, but share some state information and certainly the same
physical port.
The obvious solution is to add another layer, separating port and bus. It's
delicate surgery however.
Can you tell me how you are accessing owfs? owserver? owhttpd?

Hi,
I have got a raspberry PI running with two DS2482-100
Bus 0 DS18B20 & BAE910
Bus 1 DS18B20
My question is when I select Bus listing (top level) from owhttpd I see the
devices OK and only Bus.0 and the usual other items in the list
When I select Bus.0 I then see the devices and Bus.1 and Bus.0
So to get to the adapter owhttpd shows the following paths at the top of the
page
bus.0/bus.0/interface/settings
or the 2nd adapter is
bus.0/bus.1/interface/settings
So my question is whats the first bus.0 there for. ?
Thanks Rob
BTW. It seems to work well, its my first time playing with I2C.
