As I understand it, owfs has moved to a client-server model where one server application (owserver) talks to the 1-wire bus and client applications talk, via sockets, to the server. And while some applications still retain the capability of talking to the bus directly (the owfs executable is the prime example), some other programs in the owfs package may not have that capability. So, if you want to use some of these programs that cannot talk to the 1-wire bus, you have to run owserver first, and then point the other applications to owserver by providing IP address and port to connect to (the protocol between owserver and the ow* clients uses TCP). Personally, I have an init.d script that starts owserver like this: /opt/owfs/bin/owserver -d /dev/ttyUSB1 -C --error_print 0 --error_level 1 --nozero Since you are using that USB-based master I think you'd have to replace my "-d /dev/ttyUSB1" with just "-u". After you have owserver running, you'd run owfs with something like: /opt/owfs/bin/owfs --allow_other -C -s localhost:4304 /owfs --nozero The other utilities are run in a similar way. Hope this helps.
