Re: Permissions problems with usb as root???

Hello!
Jim, your settings resemble an interesting issue that first turned up on of
all things Debian, the udev method of assigning and managing ports.

Check to see how it on your new system is managing things. Then see how it
is working on a setup that was built the exact same way. Keep doing it that
way across your collection of systems who're all running the same operating
system.

Even though I am running Slackware and indeed using the most recent release
I do not believe I can actually reproduce your problem here. That
functionality here has always behaved itself.

Re: Permissions problems with usb as root???

I tried both of your find commands, and neither returned anything
relevant (the first returned nothing; the second returned only
firewire and wireless entries).

Re: Permissions problems with usb as root???

Unfortunately, that was one of the first things I tried...I did not
have any kernel modules ds* or *onewire* loaded anywhere...They're not
even installed.

LinkLocator on DS9490

Hi,

while playing around with a LinkLocator, just a quick question:
Is this supposed to work with any busmaster in owfs or only with the link-adapters ?

Having it attached to a DS9490 USB-Adapter with a DS1990A behind it, I see the iButton in owfs but only get
locator 0000000000000000
(instead of FF so it does at least *something*)

owfs 2.7p21
other: DS9490 busmaster, only a few ds18B20 attached

best regards

Michael

OWFS over the W1 netlink interface

Hallo,

I'm trying to get OWFS running over the W1 netlink interface to a MXC
1-wire bus-master on a ARM i.mx31 based board. The W1 of the kernel
works fine and I can see the 1-wire devices:

-bash-3.2# ls /sys/bus/w1/devices
01-0000136b5f1b  43-00000011406b  43-0000001157bd  w1_bus_master1

Unfortunately, I do not get OWFS to work:

  -bash-3.2# owfs --w1 /mnt/1-wire
  -bash-3.2# insmod mxc_w1.ko
  -bash-3.2# cd /mnt/1-wire
  -bash-3.2# ls
  settings  statistics  structure  system  uncached

owfs seems not so scan for slave devices. I even need to load the 1-wire
bus-master driver after starting owfs, otherwise it will not realize the
bus masters properly. Are there any known issue?

Thanks for help.

Wolfgang.
