1wire support

[DragonK]

it should be enough to do a: sudo /opt/owfs/bin/owfs /dev/ttyUSB0 --allow_other -C -m /home/user/1-wire

in my case this will actually mount owfs to the 1-wire directory (showing bus.0, settings, ...) but no sensor is showing up...

i see the interface in lsusb and dmesg as well.

Hi,

Pls post output of lsusb

Sorry,

dmesg to pls.
Wat else do you have connected to te usb, because that might influence wich USB device the 1-wire interface would be.
It might be /dev/ttyUSB1 or /dev/ttyUSB2.

Hari pls correct me if I'm wrong.

in my case its on ttyUSB0, here is a part of dmesg:

[   21.217743] ftdi_sio 3-2:1.0: FTDI USB Serial Device converter detected
[   21.217832] ftdi_sio: Detected FT232RL
[   21.218131] usb 3-2: FTDI USB Serial Device converter now attached to ttyUSB0

do you want to see the whole dmesg?

on USB ports I got X10 interface, second NIC and the 1-wire interface...

Are people using DS9490R?

If so, this may be causing the issue
http://owfs.org/index.php?page=usb-ds9490r

This is the device I am using

[_if_]

Hi,

the interface uses DS9097U...

thanks

That's my lsusb and if I enter dmesg I get this repeated (slight variation in values):

[Kezza]

sudo /opt/owfs/bin/owfs /dev/ttyUSB0 --allow_other -C -m /home/user/1-wire

/opt/owfs/bin/ exists but not owfs in that folder.

I believe owfs should be existing and running, is that right Hari?

you don't need to mount owfs

[_if_]

ok thanks, and how would I find out the sensors ID then?

[Kezza]

If you can track down a windows machine this is what I used

http://www.maxim-ic.com/products/ibutton/software/1wire/OneWireViewer.cfm

There is a linux version but I don't think the USB devices work with it.

[_if_]

had no success on the windows pc and on my xubuntu desktop as well 
can install and run owfs on xubuntu fine but no sensors showing up...maybe I really need to replace the interface

[_if_]

just found out I got a problem with libc-2.8.90.so on my core, any ideas what that means? I don't think that was showing up before...
